Substance air (78 % N2, 21 % O2) CO2 (g) Density of gas at STP 1.279 g/L 1.977 g/L 1. The table above gives the density of CO2 gas and air at STP. Explain the assumption that the CO2 (9) does not need to be capped while subliming and that air in the flask is being displaced as the CO2 (g) concentration increases.
