Answer 2

Answer:

2.5 moles of $O_{2}$ can be stored in 56 L cylinder at STP.

Explanation:

A mole is a unit of measurement for the amount of substance present in a sample. The Avogadro's constant is a number equal to 6.022 x 1023 particles, usually known as a mole.

1 mole of any gas occupies 22.4 L at STP.

Given volume = 56 L

Number of moles = $\frac{56}{22.4}$ = 2.5 moles

Therefore, 2.5 moles of $O_{2}$ can be stored in 56 L cylinder at STP.
