1. The problem statement, all variables and given/known data A cilinder is filled with 50mg of H2 gas. In the cilinder is a piston with a surface of 27cm The temperature of the gas equals 298K. The piston rises 2cm when the temperature rises 30 degrees. Calculate the mass of the piston Also given data: MH2=2.02g/mol Right answer: 3.6kg 2. Relevant equations Ideal gas equation : p.V = n.R.T 3. The attempt at a solution I though the volume rose with 2x27cm^2 = 54cm^3 So I used the ideal gas formula and used Volume 1 as X and Volume2 as x+54 and equaled those formulas to each other but received the wrong answer.
