Ammonia reacts with oxygen to form nitrogen dioxide and water according to the following equation: 4NH3(g) + 7O2(g) ® 4NO2(g) + 6H2O(g)
You react ammonia and oxygen, and at the end of the experiment you find that you produced 27.0 g of water, and have 8.52 g of ammonia left over. Determine the mass of oxygen reacted (3 points)

1. Convert 27.0 g H2O to moles. moles = g/molar mass.
Using the coefficients in the balanced equation, convert moles H2O to moles O2.
Now convert mols O2 to grams. grams O2 = moles O2 x molar mass O2.
