1 Quantity Relationships in Chemical Reactions 2AgNO 3 + Na 2 CO 3 Ag 2 CO 3 + 2NaNO 3 what is the ratio of the reactivity 2 molecules AgNO 3 2 moles NaNO 3 1 molecule AgNO 3 1 mole Na 2 CO 3 ex: How many moles of Na 2 CO 3 are needed to react with 22 moles of AgNO 3 ? Given: 22 moles AgNO 3 wanted: moles of NaCO 3 ex: How many grams of NaNO 3 is produced from 4.00 moles Na 2 CO 3 ? Given: 4 moles Na 2 CO 3 wanted: grams NaNO 3 m.m.: 85.0g NaNO 3 4.00 moles Na 2 CO 3 1 mole Na 2 CO 3 2 mole NaNO 3 1 mole NaNO 3 85.0 g NaNO 3 = 680 g NaNO 3 H.2 Mass Calculations Three steps to convert: How to solve a Stoichiometry problem 1. mass A moles A 2. moles A moles B (balanced formula) 3. moles B mass B 22 moles AgNO 3 1 mole Na 2 CO 3 2 mole Ag NO 3 = 11 mole Na 2 CO 3
