Pressure questions

Calculate the partial pressure of oxygen and hydrogen in a mixture of 35.0 g of oxygen gas and 11.5 g of hydrogen gas in a 2.0 L container at 35F?

Soln.

number of moles of O2 = 35/32 = 1.1 mole

number of moles of H2 = 11.5/2 = 5.75 mole

total number of moles = 1.1 + 5.75 = 6.65 mole

Total Pressure = nRT/V = \frac{6.65 x 0.082 x 274.817}{2} = 7.58 atm

mole fraction of O2 (XO2) = \frac{n_(O2)}{n_(total)} = \frac{1.1}{6.65} = 0.165

mole fraction of H2 (XO2) = \frac{n_(H2)}{n_(total)} = \frac{5.75}{6.65} = 0.864

Pa = Xa Ptotal

P_(O2) = 0.165 x 7.58 = 1.25 atm

P_(H2) = 0.864 x 7.58 = 6.55 atm
