Water vapor is a polar gas molecule. Because of this it has fairly strong interactions with itself in the gas phase that can make it behave less like an ideal gas that other gases under similar conditions. What is the difference between the calculated pressures found using the ideal gas law and found using the van der Waals gas equation for 1 mole of water vapor at -100°C in a 1.00L container. (van der Waals constants for water are a = 5.464 L2 atm mol-2, b = 0.03049 L mol-1) i atm
A 1.00 L rigid cylinder contains one mole of neon gas at 25 °C. Calculate the pressure using (a) the ideal gas law, and (b) the van der Waals equation. (c) A much more accurate equation is the virial equation, B(T) + V pVm C(T) 1+ RT Vm where B(T) and C(T) are functions of temperature. For neon at 25°C, the values of B(T) and C(T) are 11.42 cm³.mol-1 and 221 cmé.mol2, respectively. Assuming the pressure calculated using the virial equation is the "true" value, determine the percent error by using ideal gas law and van der Waals equation.

A gas of unknown molecular mass was allowed to effusethrough a small opening under constant-pressure conditions.It required 105 s for 1.0 L of the gas to effuse. Underidentical experimental conditions it required 31 s for 1.0 Lof O2 gas to effuse. Calculate the molar mass of theunknown gas. (Remember that the faster the rate of effusion,the shorter the time required for effusion of 1.0 L; inother words, rate is the amount that diffuses over the timeit takes to diffuse.)
