How do you find theoretical percent of water?

To find the theoretical percent of water in a compound, you need to determine the molar mass of the compound and the molar mass of water. Then, divide the molar mass of water by the molar mass of the compound and multiply by 100 to get the percentage.


How is percent yield caculated?

Percent yield is calculated by dividing the actual yield (the amount of product obtained in a chemical reaction) by the theoretical yield (the amount of product that should be obtained according to stoichiometry) and multiplying by 100 to get a percentage. This formula allows you to determine how efficiently a reaction was carried out by comparing the actual yield to the maximum possible yield.
