A sample of gas in a cylinder as in the example in Part A has an initial volume of 54.0 L , and you have determined that it contains 1.30 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 13.5 L . How many moles of gas (n2) remain in the cylinder
