Question

The volume occupied by a given mass of a gas at 298K is
25 ml at 1 atm pressure calculate the volume of the gas if
pressure is increased to 1.25 atm at constant temp.​

Answer 1

Answer:

volume of the gas when pressure is increased = 20 ml

Explanation:

Given

initial volume V1 = 25 ml

temperature T = 298 K

initial pressure P1 = 1 atm

final pressure P2 = 1.25 atm

final volume V2 = ??

Solution

as we know that from gas laws

P1 V1 = P2 V2 --------1

by putting values

1 X 25 = 1.25 X V2

V2 = 25 / 1.25

V2 = 20 ml

volume of the gas when pressure is increased to 1.25 atm = 20 ml
