Question

How many moles of nitrogen is needed to produce 8.2 moles of ammonia by reaction with hydrogen?

Answer 1

The chemical equation is N2+3H2———-2NH3

that is for 1 mole of N we get 2 moles of NH3

so to get 8.2 moles of NH3 we need to divide 8.2 by 2 we get 4.1

so the number of moles needed is 4.1
