A box contains 0 . 90 g of liquid water in equilibrium with water vapour at 27 ° C . The equilibrium vapour pressure of water at 27 ° C 32 . 0 Torr. When the volume of the box is increased, some of the liquid water evaporates to maintain the equilibrium pressure. If all the liquid water evaporates, then the volume of the box must be ______ litre. [nearest integer] (Given: R = 0 . 082 L atm K - 1 mol - 1 _ (

Correct answer

0

Step-by-step solution

Applying ideal gas equation, PV = nRT where ,   P =   pressure V = volume n = Number   of   moles R = Universal   gas   constant T = Temperature V = nRT P = 0 . 90 × 0 . 82 × 300 × 760 18 × 32 = 29 . 21 Litres Hence, the volume of the box is 29 litres(In integer)
