1.	How many grams of Chlorine can exert 1200 torr at room temperature in a vessel of 1.5 L capacity?
Answer» Solution :From the ideal gas EQUATION, the mass of a gas is GIVEN as, `m= (PVM)/(RT)` Substituting the values, `m=( 1200 XX 1.5 xx 71 )/( 760 xx 0.0821 xx 298 )` Mass of chlorine = 6.88grams
