Calcium dihydrogen phosphate Ca(H2PO4)2, and sodium hydrogen carbonate, NaHCO3, are ingredients of baking powder that react with each other to produce CO2, which causes dough or batter to rise:
Ca(H2PO4)2 (s) + NaHCO3 (s) CO2 (g) + H2O (g) + CaHPO4 (s) + Na2HPO4 (s) [unbalanced]
If the baking powder contains 31.0 % of NaHCO3 and 35.0 % Ca(H2PO4)2 by mass:
(a) How many moles of CO2 are produced from 0.71 g baking powder?
(b) If 1 mol of CO2 occupies 37.0 L at 350°F (a typical baking temperature) what volume of CO2 is produced from 0.71 g of baking powder?
