Solution

The correct option is A
10

Given volume = 224 L.
Molar volume at STP (litres) = 22.4 L

In case of gases at STP,

Number of moles= $\frac{Volume at STP (litres)}{Molar volume at STP (litres)}$ .... (i)

After inserting the values of volume of nitrogen at STP and molar volume of nitrogen at STP in equation (i) we have

Number of moles= $\frac{224}{22.4}$ = 10 mol.
Therefore, the number of moles present in 224 L of nitrogen at STP is 10.
