  1. I would make up a convenient number (100 for example) and say the gas mixture consists of 100 g Ne and 100 g Ar.
    Calculate moles of each.
    Calculate total moles.
    Calculate mole fraction of each.
    Then PAr = mole fraction Ar x 300
    PNe = moles fraction Ne x 300 = ??
    Post your work if you get stuck.
