Question

A chemist wishes to perform the following reaction: N2 + 3 H2 → 2 NH3 If only 14.0 g of N2 is available, what is the minimum amount, in grams, of H2 needed to completely react with this quantity of N2?

Answer 1

3 grams

Step-by-step explanation:

14 g of N2 is 1/2 mole

If you halve the N2 in the balanced equation , you have to halve the H2 down to 1.5 moles of H2 which is 3 grams
