Problem: A 128g gas sample was filled in a 50.0L closed container. At 25 degrees Celsius, the pressure inside the container was measured to be 1.95 atm.
Part A: What is the molar mass of the gas? Gas constant (R=0.0821 L atm K-1 mol-1)
I don't know how to get that solution for the above problem. Please help! Thanks.
