The pressure exerted by 12 g of an ideal gas at temperature t

∘

C in a vessel of volume V litre is 1 atm. When the temperature is increased by 10

∘

C at the same volume, the pressure increases by 10%. Calculate the volume of V.

[Molecular weight of the gas is 120. Write the value of V × 1000 Value]

ANSWER

PV=nRT

PV=nRT=

1×V=

120

12

×R×(273+t) (i)

1.1×V=

120

12

×R×(273+t+10) (ii)

Dividing equation (ii) by equation (i), we get

1.1=

(273+t)

(273+t+10)

or t=−173

∘

C

Putting this value in equation (i), we get

1×V=

120

12

×0.0821×(273−173)

or V=0.821L

∴V=x×1000=0.821×1000=821
