A gas mixture contains 4.00 grams of O2 and 4.00 grams of He. If the total pressure of the gas sample is 4.67 atm, what is the partial pressure of each component?

  • Chemistry -

    mols O2 = grams/molar mass
    mols He = grams/molar mass
    XO2 = n O2/total mols.
    XHe = n He/total mols.
    pO2 = XO2*Ptotal
    pHe = XHe*Ptotal
