A mixture contains 5.0 g of He, 1.0 g of Ar, and 3.5 g of Ne. Calculate the volume of this mixture at STP. Calculate the partial pressure of each gas in the mixture at STP.

Convert grams of each to mols. mol = grams/molar mass. Then use PV = nRT and total n to find volume at STP.
Then use PV = nRT and the volume you found to determine the partial pressure of each gas.
