An electric power station annually burns 3.1 x 107 kg of coal containing 2.4 percent sulfur by mass. Calculate the volume of SO2 emitted at STP. A concentration of 8.00 x 102 ppm by volume of CO is considered lethal to humans. Calculate the minimum mass of CO in grams that would become a lethal concentration in a closed room 17.6 m long, 8.80 m wide, and 2.64 m high. The temperature and pressure are 20.0°C and 756 mmHg, respectively. The estimated average concentration of NO2 in air is 0.016 ppm. (a) Calculate the partial pressure of the NO2 in a sample of this air when the atmospheric pressure is 755 torr (99.1 kPa). (b) How many molecules of NO2 are present under these conditions at 20 °C in a room that measures 15 x 14 x 8 ft?
