Question

A gas cy linder of capacity of 20 dm3 is filled with gas x the mass of which is 10 g .When the same cylinder is filled with hydrogen gas at the same

Answer 1

To get the relative molecular density of gas x, we should get the vapor density first. The equation for volume density is:

$Vapor density= \frac{weight of gas x}{weight of same volume of hydrogen}\\Vapor density=\frac{10}{2} \\Vapor density=5$

Relative molecular mass of gas x

=2 x vapor density

=2 x 5

=10

Therefore, the relative molecular mass of gas x is 10g.

Answer 2

Explanation:

10
