Carbonated drinks like cola, tonic water and club soda are pleasantly bubbly due to the following decomposition of carbonic acid:

H2CO3(aq) → H2O(l) + CO2(g)

If a sample of H2CO3 decomposes over water at 50°C, 0.23 L of gas is collected at 1.0 atm of pressure, how many moles was the H2CO3 sample? Account for the presence of water vapor in the collected gas; the vapor pressure of pure water at 50°C is 92.15 torr.
