The number of moles present in 224 L of nitrogen at STP is
10
Given volume = 224 L.
Molar volume at STP (litres) = 22.4 L
In case of gases at STP,
Number of moles= 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= 22422.4 = 10 mol.
Therefore, the number of moles present in 224 L of nitrogen at STP is 10.
