Question

1. A sample of gas in a cylinder as in the example in Part A has an initial volume of 48.0 L , and you have determined that it contains 1.20 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 12.0 L . How many moles of gas (n2) remain in the cylinder? Express your answer with the appropriate units. n2 =

2. A cylinder with a moveable piston contains 0.89 mol of gas and has a volume of 327 mL. What will its volume be if an additional 0.27 mol of gas is added to the cylinder? Express your answer using two significant figures. Vfinal =
