QUESTION 2 At 27 C and 1.00 atm, the density of COzla) is 1.79 gl. The rate of effusion of CO2(g) through an apparatus is 7.59 m/sec. What is the molecular mass (gimol) of an unknown gas ifit effuses at a rate of 6.92 mL/sec through the same apparatus under the same conditions? Hint Use law of effusion that relates rate of effusion to molar mass.
