questions 4 and 5 please explain
4. A cylinder with a piston originally contains 5.0 L of He gas at a temperature of 310 K. When the gas is cooled the piston moves and the new volume is 2.4 L. What is the final temperature of the gas assuming that pressure and the number of moles of He remains constant? 5. What volume, in L, is occupied by 10.0 g N, at 30.0°C and a pressure of 385 mm Hg?

there due at midnight.
Oxygen gas can be prepared by heating potassium chlorate according to the following equation 2KCIO3(s) *2KCI(s) + 302(g) The product gas, O2, is collected over water at a temperature of 25 °C and a pressure of 747 mm Hg. If the wet O2 gas formed occupies a volume of 6.91 L, the number of grams of O, formed is g. The vapor pressure of water...
