If that amount, from problem 7 , fills a room 500,000 L, then how many parts per million carbon dioxide are in the room? 1 mol of gas occupies 22.4L​

Question

If that amount, from problem 7 (the amount is the propane balanced equation: C3H8 + 5O2 = 3CO2 + 4H2O).

Answer 1

3 moles CO2 x 44 g/mole = 132 g CO2

132 g/500,000 L x 1000 mg/g = 0.264 mg/liter = 0.264 ppm
