Ammonia, NH3, can be made by reacting nitrogen and hydrogen and the equation is N2 + 3H2 --> 2NH3 How many moles of NH3 can be made if 19 moles of H2 react with enough N2? mol

Verified Answer :

Alkatoe

make a proportion
3 H2 - 2 NH3
19H2 - x
x = (19x2)/3= 12,666666

You have a balanced equation that says one mole of \(N_2\) plus three moles of \(H_2\) react to produce two moles of \(NH_3\). So if 2 moles of hydrogen are required for 3 moles of ammonia, then you can make the simplest of equations to solve this. That is,

\(3n_H=2n_A\)

Solving for the number of moles of hydrogen then

\(n_H=\frac{2}{3}n_A\)

You were given the number of moles of ammonia so plug it in and you are done!
