Question

How many liters of nitrogen oxide at STP are produced from the reaction of 59.g of NH3?

Balanced Equation:

Ammonia reacts with oxygen to produce nitrogen oxide and water.

4NH3(g)+5O2(g)→4NO(g)+6H2O(g)

Answer 1

mols NH3 = 59/molar mass NH3 = ?
Convert mols NH3 to mols NO using the coefficients in the balanced equation. That's ?mols NH3 x (4 mols NO/4 mols NH3) = ? x 1/1 = ?mols NO.
Then ? mols NO x 22.4L/mol = x L NO @ STP
