A vessel contains a mixture of nitrogen ...

A vessel contains a mixture of nitrogen of mass 7 g and carbon dioxide of mass 11 g at temperature 290 K and perssure 1 atm.Find the density of the mixture.

A

`1.1 g//L`

B

`1.2 g//L`

C

`1.515 g//L`

D

`1.6 g//L`

Text Solution

Verified by Experts

The correct Answer is:
C
)`P_(1)V=(7)/(28)xxRxx290`
`p_(2)V=(11)/(44)xxRxx290`
`therefore (P_(1)+P_(2))V=((7)/(28)+(11)/(44))Rxx290`
`before P_(1)+P_(2)=1 atm`
`V=(((7)/(28)+(11)/(44))xx8.3xx10^(7)xx290)/(1.013xx10^(6))`
`therefore Density `= (mass)/(volume)=(18)/(V)=1.515 g//L`
