For people who are looking at this in the future: the reason the above answers differ is due to a minor miscalculation of the molar mass of KHP. Look up the molar mass of KHP online, or get an official value from your instructor.
It's approximately The first thing you need to do is write a balanced equation for the reaction which is as follows:.

Molar mass of KHP is Computing molar mass molar weight To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula you may use: Any chemical element. Common compound names. Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.
Computing molecular weight molecular mass To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets. Examples of molecular weight computations: CO2SO2.
Definitions of molecular mass, molecular weight, molar mass and molar weight Molecular mass molecular weight is the mass of one molecule of a substance and is expressed in the unified atomic mass units u.

It forms white powder, colorless crystals, a colorless solution, and an ionic solid that is the monopotassium salt of phthalic acid. KHP is slightly acidicand it is often used as a primary standard for acid-base titrations because it is solid and air-stable, making it easy to weigh accurately.
It is not hygroscopic. It also serves as a thermal standard in thermogravimetric analysis . Most TOC analyzers are based on the oxidation of organics to carbon dioxide and water, with subsequent quantitation of the carbon dioxide.
Many TOC analysts suggest testing their instruments with two standards: one typically easy for the instrument to oxidize KHPand one more difficult to oxidize. For the latter, benzoquinone is suggested. From Wikipedia, the free encyclopedia. CAS Number. Interactive image. PubChem CID. Chemical formula.

Main hazards. External MSDS. R-phrases outdated. R36 R37 RIn chemistry, the formula weight is a quantity computed by multiplying the atomic weight in atomic mass units of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance.
The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.
If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom or group of atoms in the formula by the formula weight and multiplying by We use the most common isotopes.
This is how to calculate molar mass average molecular weightwhich is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.
Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights. A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying to convert.
The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass. Molecular weight of KHP.Settlement is based on the official score(s) of the specified batsman. Any quoted player, who takes no part in the specified series, will be void (market may be subject to a Rule 4 (Deduction)). In the event of two or more players ending on an equal number of wickets, then the bowler with the least number of runs conceded will be the winner.
In matches affected by adverse weather bets will be governed by the official competition rules with the following exception: if a match is decided on either a bowl out or the toss of a coin then all bets will be void.
Where no price is quoted for the tie and the official competition rules do not determine a winner then Dead-Heat rules will apply, in competitions where a bowl out or super over determines a winner then bets will be settled on the official result. The result of a match is a tie when the scores are equal at the conclusion of play, but only if the side batting last has completed its innings (i. If a match is abandoned due to outside interference then bets will be void unless a winner is declared based on the official competition rules.
In the event of a change of opponent from the one advertised then all bets for that match are void. If a match is cancelled then all bets will be void if it is not replayed within 36 hours of its advertised start time. Bets void if the designated number of matches changes, unless settlement of bets is already determined. If a series is drawn and no draw option is offered, bets will be void. Bets stand unless either of the listed players do not open the batting, then all bets are void.
Bets stand, regardless of which of the listed players faces the 1st ball. If neither player reaches 10 runs then the option Neither is the winner. In weather affected matches, if neither of the batsmen reaches 10 runs and either are Not-Out then bets void. If neither of the batsmen reaches 10 runs and both are Out then Neither is the winning option. The handicap is added at the end of the match. If the team batting first wins or ties the match then Runs Handicap will be used for settlement purposes.
If team batting second wins the match then Wickets Handicap will be used for settlement purposes. If a match is abandoned due to outside interference then bets will be void.
If the match is affected by weather or any other delay and overs are reduced in either innings then all bets will be void. Bets placed on any player not in the starting 11 or nominated as the designated substitute 12th man are void. Bets on players who are selected but do not bat or field will be settled as losers.
The following number of minimum overs must be bowled unless All Out or match has been completed, otherwise bets void.
If no bowler takes a wicket, all bets will be void.Pay the Ones (6) odds Analysis Will be a close run race between the top picks. R3 1660m Class: Class 1, Handicap 2:50PM Selections 2.
