What is the density of a gas at STP that has a molar mass of 50.0 g/mol? Student A wrote some preliminary notes: PV = nRT; n = m/M; and d = m/V

known: unknown

T = 273 K d = g/cm3

P = 1 atm

R = 0.08125 atm

M = 50.0 g/mol

If PV = nRT and n = m/M, what is the density of the ideal gas?

Help Student A find the equation to use to solve this problem:
