Volume of nitrogen gas is 125ml atmospheric pressure is 763mm Hg the water temperature inside the eudiometer is the same as the level of the water in the beaker.

Calculate the volume if the nitrogen at STP.
P1V1/T1=P2V2/T2

1 answer

That formula will work if you want the volume of the wet nitrogen, if you want the volume of dry N2 gas you will need to correct for that.
