We’re being asked to calculate for the partial pressure of H2, CO2, and O2 in a 5.00-L container and the total pressure in the container.


We’re going to calculate the pressure of each gas first using the ideal gas equation:

PV=nRT

P = pressure, atm
V = volume, L
n = moles, mol
R = gas constant = 0.08206 (L·atm)/(mol·K)
T = temperature, K

Rearranging the ideal gas equation:

PVV=nRTVP=nRTV
