Note the correct spelling of celsius.
Total pressure 750 mm Hg.
750 = Pdry gas + PH2O vapor
750 = Pdry gas + 14
P dry gass = ??
Now convert to STP using (P1V1/T1) = (P2V2/T2)
My quickie estimate is about 45 cc but that is an exact answer.
A gas 'x' is collected over water at 17 degree celcius and 750 mm pressure.If the volume of the gas collected is 50 cc then calculate the volume of the dry gas at standard temperature pressure and at 17 degree celcius the vapour of pressure is 14 mm

p1=total press.- p2=760mm
vapor press. v2=?
=(750-14)mm t2=273k
=736mm
v1=50cc
t1=(17+273)k
=290k
USE FORMULA- p1v1/t1=p2v2/t2
ANSWER - 45.58cc

ANSWER - 45.58cc
p1 = total pressure - vapour pressure
= 750-14 mm pressure
= 736 mm pressure
v1 = 50cc
t1 = 290K
p2 = 760 mm pressure
t2 = 273K
v2 = ??
Using P1*V1/T1 = P2*V2/T2, we get
V2 = 45.58cc (approx)
Hope that helps!
