Question

the vapour density of gas is 40.calculate the volume of 20g of this gas​

Answer 1

Answer:

The SI unit of density is g/cm³.

Explanation:

So, the density given = 40g/cm³

Then volume of 40 g gas = 1cm³,

Then, volume of 20 gram of this gas =

$\frac{1 \times 20}{40} = \frac{1}{2} {cm}^{3}$

Or, 0.5 cm³

That's the answer.

Answer 2

Answer:

So, the density given = 40g/cm³

Then volume of 40 g gas = 1cm³,

Then, volume of 20 gram of this gas =

\frac{1 \times 20}{40} = \frac{1}{2} {cm}^{3}
