what will be the effect on the calculated molar
mass of the gas if the effect of the water vapour is
ignored. It will be

collection flask
(2) High because of omitting the vapour pressure
of the water in the calculation
(3) Low because of the mass of water in the
collection flask
(4) Low because of omitting the vapour pressure
of the water in the calculation​
