# Ideal Gas Equation

When an evacuated glass vessel weighing 134.74g was filled with an unknown gas Y the pressure was found to be 99.3kNm-2 at 31•C, while the mass was 137.28 g. The glass vessel was then filled completely with water and the mass was 1067.90g. By using the ideal gas equation, determine the relative molecular mass of gas Y.
