Question

272 cm³ of carbon(IV) oxide were collected
over water at 15°C and 782 mm Hg pressure,
Calculate the volume of the dry gas at s.t.p.
(S.V.P. of water at 15°C is 12 mm Hg)​

Answer 1

Answer:

V1=272cm3

P1=782mm hg

P2=760 monthly +12mm hg=772mm hg

V2=?

using Boyle's law

p1v1=p2v2

(782)(272)=(772)(V2)

V2=275.52cm3
