Question

One gram mole of a gas at STP occupies 22.4L volume. This fact is derived from___.

• A. Daltion’s theory
• B. Avogadro’s hypothesis
• C. Berzelius hypothesis
• D. None of the above

Answer 1

The correct option is B

Avogadro’s hypothesis

1 mole of all gases at constant temperature and pressure occupy the same volume

One mole of a gas at STP occupies 22.4L.

One mole of hydrogen gas is 2.016g

2.016g→ 22.4L

1g → y

Calculate y.

y = (1 x 22.4)/ 2.016

y = 11.11L
