50 cm3 of gas was collected over water at 10ºC and 765 mm Hg. Calculate the volume of the gas at s.t.p. if the saturated vapour pressure of water at 10ºC is 5mm Hg
49.19 cm 3
48.87 cm 3
48.55 cm 3
48.23 cm 3
Correct answer is D
General Gas Equation:
P1V1T1 = P2V2T2
where P1 = 765 - 5 = 760mmhg
V2=P1V1T2P2T1
V2=760∗50∗273760∗283 → 48.23cm3
