1.In one litre of helium gas at 25 °C, there are 0.04 moles of helium. At the same temperature and pressure, how many moles of carbon dioxide would there be in 0.5 litres?

2.If there are 0.02 moles of argon gas in a 0.4 litre container, at a pressure of 100 kPa, how many moles of oxygen would there be in a 0.8 litre container at the same temperature and pressure?

3.Consider what you know about kinetic molecular theory and Avogardo's Hypothesis. If you were to blow up a balloon all the way, and then take it into a colder environment, what would happen there?
