Question

How many molecules of NH3 are produced when 3.00 moles of H2 react completely in the following equation?

N2 + 3H2 → 2NH3

Answer 1

give that you have xss N2?

set up a ratio using the ratio of moles in the balanced reaction (coefficients)

so for every 3 moles of H2 you make 2 mols of NH3

y mol/3 H2 = xmol/2 NH3

you know you have 3 moles of H2

3 mol/3 = x mol/ 2

x mol = ((3)(2))/3
