Answer #1

Solution:

Equation for the density of a gas, d = PM / RT

Pressure, P = 715 torr = 0.940789 atm

Molar mass of gas, M = 96.48 g/mol

Gas constant, R = 0.082057 atm.L / K. mole

Temperature, T = 273.15 + 142 = 415.15 K

The density of a gas, d = (0.940789 * 96.48) / (0.082057 * 415.15)

                                     = 2.66 g / L

The density of a gas is 2.66 g / L
