Question

14g of nitrogen at STP

Answer 1

Hello!

1 mol N= 14g N

But it's always in the form of N2.

In STP 1mol N gas = 22.4 Liter N

1 mol N gas= 28g N (Because N2 is formed in nitrogen gas and molecules form gas/liquid/solid. Here the N molecule is N2)

28g N= 22.4 Litre N

14g N= 11.2 Liter N

If you find it helpful then I'm glad.
