# The Ideal Gas Law to Determine the Molecular Weights of Gas

At a given temperature a certain number of grams of CH4, when placed in a 10 L vessel, exerts a pressure of 0.240 atm. An equal number of grams of gas B, when placed in a 12 L container at the same temperature, exerts a pressure of 0.145 atm. Calculate the approximate molecular weight of gas B.
