From the given equation, we have the general form of the equation of state for a real gas.
To find the mass of the gas, we use the ideal gas law for an approximation of molar mass.
The equation for pressure is: where is the gas constant, is temperature, is molar volume, and and are constants specific to the gas. Using the ideal gas law approximation and solving for the mass, we find that the mass of the gas is .
Thus, the correct answer is (b).
