need help with understanding what the questions are asking, and how to answer them:
1. Provide evidence to support Avogadro's constant law concerning the number of molecules of gases given in volumes
2. Assume that a cylinder fitted with a movable piston contains enough oxygen molecules to exert a pressure of 50 kPa when the volume is 1 litre. If four times as many molecules of hydrogen and five times any many molecules of nitrogen are introduced into the cylinder with the oxygen, no reaction occurs and temperature is constant.
(a) What will be the total pressure be if the volume is maintained at 1 Litre?
(b) What will the total volume be be if the pressure maintained at 50 kPa?
