Problem
A volume of 95 mL N2O at 27°C is collected in a graduated tube over mercury, the level of Hg inside the tube being 60 mm above the outside mercury level when barometer reads 750 mm.
(a) Calculate the volume of the same mass at STP.
(b) What volume would the same mass of gas occupy at 40°C when the barometric pressure is 745 mm and the level of Hg inside the tube 25 mm below the outside level?
