A mixture contains 5.00 g each of O2, N2, CO2, and Ne gas. Calculate the volume of this mixture at STP. Calculate the partial pressure of each gas in the mixture at STP.
Convert 5.00 g each gas to moles. moles = grams/molar mass
Use PV = nRT to calculate volume at STP using total n.
Calculate mole fraction of each gas.
Pgas = XgasPtotal.
