Professional divers sometimes use heliox, consisting of 79% helium and 21% oxygen by mole. Suppose a perfectly rigid scuba tank with a volume of 11 L contains heliox at an absolute pressure of 2.1 × 107 Pa at a temperature of 31 °C . (a) How many moles of helium and how many moles of oxygen are in the tank? (b) The diver goes down to a point where the sea temperature is 27 °Cwhile using a negligible amount of the mixture. As the gas in the tank reaches this new temperature, how much heat is removed from it?
