Answer 1

Answer:

2

Explanation:

Answer 2

The correct answer is: Both assertion and reason are correct and the reason is the correct explanation of assertion.

• STP is standard temperature and pressure, at which 1 mole of any gas occupies a volume of 22.4 litres.
• Thus, the reason statement is correct.
• In one mole of hydrogen gas, 6.023 × 10²³ molecules of the gas are present.
• Thus, we can conclude that the volume of 6.023 × 10²³ molecules of hydrogen is 22.4 litres at STP.
• Thus, both reason and assertion statement are correct and reason correctly explains assertion.
