8.81) How many moles of a gas will occupy a volume of 0.61 L ata temperature of 331 K and a pressure of 3.0 atm ?
8.112) Part A. When fully inflated, a hot-air balloon has avolume of 1.6×105L at an average temperature of 395 K and 0.967 atm. Assuming that air has an average molar mass of 29 g/mol, what isthe density of the air in the hot-air balloon?
Part B) How does this compare with the density of air at STP?It's less dense than at STP. It's more dense than at STP.
