Question

The number of molecules in 8.96 litres of gas at 0°C and 1 atm. pressure is approximately ______.

विकल्प

• 6.023 × 10²³

• 12.04 × 10²³

• 18.06 × 10²³

• 24.08 × 10²²

Answer 1

The number of molecules in 8.96 litres of gas at 0°C and 1 atm. pressure is approximately 24.08 × 10²².

Explanation:

At S.T.P. 22.4 litre of gas contains 6.023 × 10²³ molecules.

∴ Molecules in 8.96 litres of gas

= `(6.023 xx 10^23 xx 8.96)/22.4`

= 24.08 × 10²²
