Baking soda (NaHCO3, 84.0 g/mol) can react with acids such as lactic acid (HC 3H5O3, 90.1 g/mol) to generate the carbon dioxide gas needed to make baked goods rise.If sufficient lactic acid is present to completely react with 20.4 g NaHCO3, how many moles of CO2 (44.01 g/mol) are generated?
HC3 H5O3 (aq) + NaHCO3 (s) H2O(l) + CO2 (g) + NaC3H5O3 (aq)
A) 0.464 mol
B) 0.243 mol
C) 0.334 mol
D) 0.204 mol
E) 0.232 mol
