Question

what volume would one mole of hydrogen occupy at S.T.P?
(a) 11.2 dm3
(b) 22.4 dm3
(c) 33.6 dm3
(d) 44 dm3
​

Answer 1

Answer:

b) 22.4 dm3 litres

At STP, one mole of any gas occupies 22.4 litres of volume.

One mole of a gas is given by the Avogadro's number

i.e. NA and it is given as 6.023×1023.

According to this, one mole of hydrogen gas at STP will occupy 22.4 L of volume.
