It would take up the volume of the container it was in. If you want to find the volume of the water vapor at a certain pressure, you can use the Idea Gas Law: PV = nRT, where P is pressure in Atm, V is volume in L, n is the number of moles (18 mL of water is about 1 mole), R is the ideal gas constant(0.08206 L*Atm/mol*K), and T is the temperature in Kelvin (temperature in Celsius plus 273.16).

volume is not equal to mass. a gas will expand or contract depending on the temperature and pressure of its surroundings. the same amount of water is there it's just more spread out.
