50cm3 of hydrogen is collected over water at 17 degree celsius and 750 mm Hg pressure.Calculate the volume of

Question

dry gas at S.T.P.The water vapour pressure at 17 degree celsius
is 14 mm Hg?

Answer 1

Use (P1V1/T1) = (P2V2/T2)
For P1 use 750-14 = ?
V1 = 50 cc
T1 = 273+17 = ?
P2 and T2 ae STP
V2 = solve for this in cc.

Answer 2

45.6cm^3

Answer 3

48cc

Answer 4

45.58cc

Answer 5

45.6cc
