A container holds 22.4 litre of a gas at 1 atmospheric pressure and at 0ºC. The gas consists of a mixture of argon, oxygen and sulphur dioxide in which :
Text Solution
Verified by ExpertsThe correct answer is:
B
(2.201 g/L)
Let moles of Ar = x
Moles of O 2 = y
Moles of SO 2 = 1 – (x + y)
Total moles of mixture = 
1 – (x + y) = y + x ⇒ 1 = 2 x + 2y
y = 2 × x 1 = 2x + 4x
x = 
y = 
M mix = 
= 49.33
f = 
= 
= 2.2 g/L
