Question

The pressure exerted by a non-reactive gaseous mixture of

6.4 g

of methane and

8.8 g

of carbon dioxide in a

10 L

vessel at

27^{\circ} C

is

________kPa

.
(Round off to the Nearest Integer).
[Assume gases are ideal,

R = 8.314 J mol^{- 1} K^{- 1}

Atomic masses :

: C : 12.0 u, H : 1.0 u, O : 16.0 u]

Accepted Answer

Correct answer: 150. (150) Total moles of gases, n=n_ CH_4+n_ CO_2 = 6.416+ 8.844=0.6 P= nRTV= 0.6 8.314 30010 10^-3 Now, =1.49652 10^5 Pa=149.652 kPa ≈150 kPa
