To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. A chemical engineer places a mixture of noble gases consisting of 4.50 g of He, 15.0 g of Ne, and 33.6 g of Kr in a piston-cylinder assembly at STP. Calculate the partial pressure of each gas.
PHe = __atm
PNe = __atm
PKr = __atm

    There are a couple of ways to do this but the easiest probably is to use PV = nRT for each gas.
    n for He = 4.50 g/4.003, plug in STP conditions and solve for P.
    Same process for each of the others.

    none of yall be helpin out
