# Problem: An environmental chemist sampling industrial exhaust gases from a coal-burning plant collects a CO2-SO2-H2O mixture in a 21.0-L steel tank until the pressure reaches 821.2 torr at 46.0°C. (a) How many moles of gas are collected?     (b) If the SO2 concentration in the mixture is 1.57 x 103 parts per million by volume (ppmv), what is its partial pressure in torr? (Hint: ppmv = volume of component/volume of mixture) x 106.)
