Calculate the flask filled with stop cock is evacuated and weight its mean is found to be 134.567 it is them filled to a pressure of 735 mm at31c with is of UN non molecular mass and then the flask the filled with water and weight again its mass is now 1067.9g a summary that the gas is ideal calculate the molar mass of the gas.
