lord [1]

Answer : 

As Per Given Information

Given volume of O₂ is 53 L

We've been asked to find the number of moles of O₂ gas contained

For finding the number of moles the following formulae is use

$\\ \bullet{\boxed{\blue{\bf{Number \: of \: moles = \frac{Given \: volume}{22.4} }}}}$

Put the given value we obtain

$\sf \dashrightarrow \: number \: of \: moles \: = \frac{53}{22.4} \\ \\ \sf \dashrightarrow \: number \: of \: moles \: = 2.366$

So, the number of moles is 2.366 .
