The density of CO2 gas at 27 C and 1 atm is 1.79 g dm ^ -3. The rate of release of CO2 gas through a small hole is 7.50 cm3 s ^ -1. Under the same conditions, an unknown gas of the same volume emits from the same orifice with a speed of 6.90 cm3 s ^ -1. What is the density and molar mass of the unknown gas?
