Assume that temperature and pressure are held constant for the following.
1. Determine the volume of 3.3 moles of hydrogen gas that is initially 5.7 moles at 7.53 L.
2. How many moles of CO2 will be left in a balloon that starts with 1.8 moles at 31 L when gas is allowed to escape
to a volume of 25L?
3. A flexible container contains 6.02 x 1023 molecules of N, at a volume of 22.4L. What will be its new volume if the
number of molecules is increased to 1.20 x 102?
4. A balloom starts with 5.8 x 10 molecules of N>O at 3.2-L What will-be the new-volume if the number of
molecules is tripled?
5, How many molecules.of NH3 will.be left in a balloon that is deflated_to 0.5 L? The balloon starts with 7.8 x 1024
molecules at 46 L.
