Hello, yes, you need to use PV = nRT. There are 2 ways you can do this: (1) Find partial pressures of each gas and then add them....i.e. (a) convert mass to moles for each gas, then (b)use PV=nRT to calculate partial pressure of each gas and (c) add the pressures to get the total. or (2) find total number of moles of the gases (n) and then use PV = n RT
