  1. n Ne = grams/molar mass = ?
    n Aar = grams/molar mass = ?

    Then PV = mRT and use n Ne to solve for pNe. Use n for Ar to solve for pAr.

  2. 10.0 g Ne / 20.18 g/mol = 0.496 mol
    P*1.55 L = 0.496 mol * 0.08206 L*atm/mol*K * 298 K
    P of Ne = 7.82 atm

    10.0 g Ar / 39.948 g/mol = 0.25 mol
    P*1.55 L = 0.25 mol * 0.08206 L*atm/mol*K * 298 K
    P of Ar = 3.94 atm
