Answer to Question 1

ANS: C
Water vapor pressure does not follow Dalton's law because such pressure primarily depends upon temperature. Water vapor pressure must be subtracted from the total pressure of a given mixture if the gas mixture is saturated with water.

Answer to Question 2

ANS: A
1 mole of oxygen (mw = 32 g) occupies a volume of 22.4 L and contains 6.02  1023 molecules when measured at 0 C (273 K) and 1 atm.
