Part A
A cylinder, with a piston pressing down with a constant pressure, is filled with 2.20 moles of a gas (n1), and its volume is 40.0 L (V1). If 0.500 mole of gas leak out, and the pressure and temperature remain the same, what is the final volume of the gas inside the cylinder?

Part B
A sample of gas in a cylinder as in the example in Part A has an initial volume of 52.0 L , and you have determined that it contains 1.70 moles of gas. The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the volume has changed to 13.0 L . How many moles of gas (n2) remain in the cylinder?

It is based on Avogadro's hypotheses
Equal volumes of all gases contain equal number of moles and molecules at constant temperature and pressure.
