A 10 g mixture of hydrogen and helium is contained in a vessel of capacity 0.0125 m 3 at 6 bar and 27°C. The mass of helium in the mixture is _______g. (nearest integer)
Given : R = 8.3 JK -1 mol -1 (Atomic masses of H and He are lu and 4u, respectively)
Text Solution
Verified by ExpertsThe correct answer is:
8
(8)
Let mole of He = x
Mole of H 2 = 3 -x
4x + 2(3 - x) = 10
x=2mol
Mass of He = 8g
