Question 304: Thermodynamics & KTG

Question

A cylindrical container of volume 4.0 $	imes$ 10
$-$3
m
3
contains one mole of hydrogen and two moles of carbon dioxide. Assume the temperature of the mixture is 400 K. The pressure of the mixture of gases is :
[Take gas constant as 8.3 J mol
$-$1
K
$-$1
]

Accepted Answer

V = 4 $	imes$ 10
$-$3
m
3
n = 3 moles
T = 400 K
PV = nRT $\Rightarrow$ P = ${{nRT} \over V}$
P = ${{3 	imes 8.3 	imes 400} \over {4 	imes {{10}^{ - 3}}}}$
= 24.9 $	imes$ 10

Thermodynamics & KTG

A cylindrical container of volume 4.0 \times 10 -3 m 3 contains one mole of hydrogen and two moles of carbon dioxide. Assume the temperature of the mixture is 400 K. The pressure of the mixture of gases is : [Take gas constant as 8.3 J mol -1 K -1 ]
