How many grams of sodium bicarbonate mut be decomposed by: HCl (ag) + NaHCO3 (ag) ----> NaCl (ag) + CO2 (g) + H2O (l) to yield 75.0 mL of carbon dioxide at STP?

I started to use PV=nRT. So, n = (.930 atm)(.04852 L) ------------------ = 1.86 x 10^ -3 (.0821) (296 K) mol I multiplied that by 84 g/mol (molar mass of sodium bicarbonate) and then by 100%....which equated to 15.62%. That seems off to me. Do you know what I'm doing wrong?

A 3.23 gram sample of a sodium bicarbonate mixture was reacted with excess acid. 48.52 mL of the evolved gas was collected of the water at .930 atm. and 23.0 degrees C. What is the percentage of sodium bicarbonate in the original mixture?

So I'm a bit confused. What's the difference between penance and penitence? Are they essentially the same thing? Thank you everyone.
