  1. STOICHIOMETRY Moles and Mass & Mass to Mass

  2. 2LiOH + CO2 Li2CO3 + H2O • Mass and Moles - Determine the mass in grams of carbon dioxide removed if the reaction involves 42.0 mol LiOH.

  3. 2LiOH + CO2 Li2CO3 + H2O • Mass and Moles - Determine the mass in grams of carbon dioxide removed if the reaction involves 42.0 mol LiOH. 1 mol CO2 ------------ 44 g CO2 42 mol LiOH ------------ = x ----------------- x ----------------- 1 mol CO2 ------------ 2 mol LiOH ------------ 42 mol LiOH x 1 mol CO2 x 44 g CO2 __________________________________ 2 mol LiOH x 1 mol CO2 924 g CO2 =

  4. C2H4 + 3 O2 2 CO2 + 2 H2O • Mass to Mass - If you start with 45 grams of ethylene (C2H4), how many grams of carbon dioxide will be produced?

  5. C2H4 + 3 O2 2 CO2 + 2 H2O • Mass to Mass - If you start with 45 grams of ethylene (C2H4), how many grams of carbon dioxide will be produced? 1 mol C2H4 ------------ 2 mol CO2 ------------ 44 g CO2 45 g C2H4 ------------ = x ----------------- x ----------------- x ----------------- 28 g C2H4 ------------ 1 mol C2H4 ------------ 1 mol CO2 ------------ 45 g C2H4 x 1 mol C2H4 x 1 mol CO2 x 44 g CO2 __________________________________ 28 g C2H4 x 1 mol C2H4 x1 mol CO2 141 g CO2 =
