Stoichiometry: moles to mass Unit Seven, Day Two Kimrey 13 November 2012
What is stoichiometry? • Stoichiometry is the study of the quantitative relationships in reactions. • Use mole ratios (the coefficients) to convert between one substance to another in a BALANCED equation.
Steps for stoichiometry • Balance the equation • Convert to moles if you don’t have moles • Use, and only use, the mole ratio to convert between substances.
Grams to moles • N2 + H2 NH3 • Using the above reaction. How many moles of ammonia is produced from 55.78 grams of nitrogen?
Moles to grams • Zn + HCl ZnCl2 + H2 • Using the above reaction. How many grams of zinc chloride would be produced from 9.87 moles of zinc metal?
Grams to grams • H2 + O2 H2O • Using the above reaction. How many grams of water will be produced from 56.78 grams of oxygen?
