Answer #1

22)

rHe/rN2 = (32/4)1/2

rHe = 2√2 rN2

So, Helium will effuse 2.83 times the Nitrogen.

23) At constant T and P

V1/m1 = V2/m2

22.4/4.0 = V2/3.0

V2 = 16.8 L

    A gas of unknown molecular mass was allowed to effuse through a small opening under constant pressure conditions. It required 52 s for 1.0 L of the gas to effuse. Under identical experimental conditions it required 27 s for 1.0 L of O2 gas to effuse. Calculate the molar mass of the unknown gas. (Remember that the faster the rate of effusion, the shorter the time required for effusion of 1.0 L; that is, rate and time are inversely proportional.)...
