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

Initially, a sealed balloon filled with helium gas at 20.0 °C occupies 2.91 L at 1.00 atm. The balloon is then immersed in liquid nitrogen at −196 °C, raising the pressure to 5.20 atm. What is the volume (in L) of the balloon in the liquid nitrogen? Group of answer choices 3.98 L 0.000669 L 5.48 L 0.147 L 2.13 L

A helium balloon rises from the ground where the temperature and pressure are 23 °C and 1.0 atm. When the balloon reaches a height of 1 km, the temperature and pressure have both decreased to 13 °C and 0.90 atm. Assuming that the helium behaves as an ideal gas, predict the volume of the balloon at 1 km if its initial volume was 2.1 L. any heplp would be appreciated.

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.)...
