The number of moles of oxygen in one litre of air containing 21% oxygen by volume in standard condition is

Options:

Answer:

Solution:

Air containing 21% oxygen in one litre $= \frac{21}{100} = 0.21$ litre
1 mole occupies a volume = 22.4 litre
x mole occupies a volume = 0.21 litre
So $x = \frac{V}{22.4} = \frac{0.21}{22.4} = 0.0093$ mole of $O_{2}$ .
