Hydroxylamine, NH2OH, reduces nitric oxide in what is known as comproportionation reaction (opposite of disproportionation):

2NO(g) + 4NH2OH(l) > 3N2(g) + 6H2O(l)

If the percent yield of N2 is known to be 59.1%, how many grams of H2O will be produced in the reaction between 2.39g of NO and 2.40g of NH2OH.
