Stoichiometry - Moles to Grams
This is the second of four stoichiometry worksheets. In this worksheet, students will have the added step of converting grams of a reactant or product to moles before performing the stoichiometric conversions.
Essential concepts: Stoichiometry, moles, molar ratios, mole conversions, molar mass.
Answer key: Included in the chemistry instructor resources subscription. Click here for details.

To convert moles into grams, determine the number of moles preset and the molar mass of the compound. Multiply the number of moles by the molar mass to obtain the final answer in grams.
A mole is a unit of measurement that is associated with the mass of a chemical substance. The mole is a specific measurement of the amount of atoms or molecules in a substance, based on the amount of atoms in 12 grams of carbon-12.
There are 55.346 moles in 1 liter of pure water. This is calculated by dividing the density of water, which is 997.07 grams per liter, by the molecular mass of water, which is 18.02 grams per mole.

A worksheet teaching how to do mole-to-gram or gram-to-mole stoichiometry problems.
Three conversions to remember about chemicals – usually used when we are asking about just one chemical: 1. How many atoms are in 40.08 grams of calcium?
9). How many grams are in 4.5 moles of sodium fluoride, NaF? (molar mass of NaF is 22.99 + 19.00 = 41.99 g/ mole). 4.5 moles x 41.99 grams = 188.955 g NaF
If you have grams of a chemical and want grams of a different one. 1) Convert from grams to moles. 2) Convert moles of one chemical into moles of another
