calculate the volume at STP occupied by 10²¹
molecules of Oxygen?

Solution

The molar volume that is the volume occupied by one mole of gas is 22.4 L. We know there are 6.022 X 10²³ particles of a substance in one mole of that substance. Thus
volume occupied by 6.022 X 10²³ molecules of oxygen = 22.4 L
volume occupied by 1 molecule of oxygen = 22.4 / (6.022 X 10²³)
volume occupied by 10²¹ molecules of oxygen = [(22.4 X 10²¹) / (6.022 X 10²³)]
= 3.72 X 10^-2 L = 37.2 ml
