a mixture of 1.00 grams hydrogen gas and 1.00 grams helium is placed in a 1.00 L container at 27 degrees cesius. Calculate the partial pressure and total pressure

Answer 1

PV = nRT, calculate partial pressure for hydrogen.
PV = nRT, calculate partial pressure for He.
Total P = PH2 + PHe.

Answer 2

P H2 = 1.23atm

P He = 6.163atm

P total = 7.39atm
