How can one determine the molar mass of a substance by considering its density, pressure, and temperature?

To determine the molar mass of a substance using density, pressure, and temperature, one can use the ideal gas law equation, PV nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. By rearranging the equation to solve for molar mass (M), M (mRT)/(PV), where m is the mass of the substance, one can calculate the molar mass by plugging in the given values for density, pressure, and temperature.
