Question

1 L of any gas would weigh how many times its vapour density.

Options

• 22.4

• 0.089

• 11.2

• 2.24

Answer 1

0.089

Explanation:

Since Vapour Density = `"Mass of 1 L of gas at S.T.P."/("Mass of 1 L of"  H_2 " gas at S.T.P. (0.089 g)"`, the mass of 1 L of any gas is 0.089 × Vapour Density.
