NaHCO3 + HCl ==> NaCl + H2O + CO2
mols HCl = M x L = ?
Use the coefficients in the balanced equation to convert mols HCl to mols CO2.
Then use PV = nRT to convert mols CO2 to L at the conditions listed.
Alka-Seltzer contains the base sodium hydrogen carbonate, NaHCO3, which reacts with hydrochloric acid in the stomach to yield sodium chloride, carbon dioxide, and water. What volume of CO2 gas at 104.5 kPa and 311 K would be formed when 10.0 mL of 1.0 M HCl is mixed with an excess of NaHCO3?
