  1. calculate the moles of each gas.
    partial pressure Ne= molesNe/totalmoles * 765torr
    partial pressure Ar= molesAr/totalmoles * 765 torr

    total moles= moles of each added up. Just looking at the answers, and knowing there are many more moles of Ne than Ar (argon has twice atomic mass as Ne), my guess is 257torr, for Ar pressure. Work it out.
