Question

a balloon contain 0.02gram of hydrogen gas it contain hydrogen molecules
​

Answer 1

Explanation:

From ideal gas equation PV=nRT,

Here, assume mass of helium in mixture is x, then mass of hydrogen is (5-x) so, 2×10

5

×0.02=((5−x)/2+x/4)8.314×293.

x=3.43and5−x=1.57.

So ratio of hydrogen to helium is 1:2.

then x+ y = 3
