Chemistry (partial pressure)

A mixture consists of 3.2 grams of CH4 gas and 1.2 grams of H2 in a steel container. The pressure inside the container is 6.0 atm. The molecular mass of CH4 is 16 g/mol, and the molecular mass of H2 gas is 2 g/mol.

What is the partial pressure of H2?

  1. moles CH4=3.2/16=.2
    moles H2=1.2/2=.6
    mole ratio CH4/H2=1/3

    so the pressure is 6atm, consisting of four parts, three of which are H2, and one which is CH4
    those are the partial pressures.
