If 9.006g of a gas are enclosed in a 50L vessel at 273.15K and 2atm of pressure. What is the molarmass and gas

Answer 1

PV = g/MM *RT
MM = gRT/PV = 9.006*0.08206*273/(2 atm * 50L) = 2.018 g/mol

Hydrogen gas.

And Ed the Science Guy needs to go back to school if he can't figure out how to get molar mass from the Ideal Gas Law given all of the information you provided.

Answer 2

Not possible to calculate unless we know what the gas is. We need to calculate the number of moles (n) in PV = nRT but 9.006g cannot be used.
