Answer 2

The number of moles of oxygen gas having given volume is 0.005 moles

Explanation:

At STP:

22.4 L of volume is occupied by 1 mole of a gas

We are given:

Volume of oxygen gas = $112cm^3=0.112L$   (Conversion factor:  $1L=1000cm^3$ )

Applying unitary method:

22.4 L of volume is occupied by 1 mole of a gas

So, 0.112 L of volume will be occupied by = $\frac{1}{22.4}\times 0.112=0.005mol$ of oxygen gas
