Question

Equal masses of Ne and H2 gases are mixed in a vessel. The mole fraction of Ne in the mixture is
A) 0.09
B) 0.9
C) 0.16
D) 1.3

Answer 1

Answer:

$a) \: 0.09$

Explanation:

equal mass mean

no mole of Ne =given mass/molar mass

no of mole =20/20=1 mole of Ne

no of mole of H2 =20/2=10 mole of H2

mole fraction= 1/11= 0.09
