Question #172091

Ammonia NH3 chemically reacts with oxygen gas O2 to produce nitric oxide NO and water H2O.

What mass of water is produced by the reaction of 2.1g of oxygen gas?


Expert's answer

5O2 + 4NH3 = 6H2O + 4NO

5O2 = 6H2O

5 × 32g O2 = 6 × 18g H2O

1g O2 = 6×18/(5×32)g H2O

2.1g O2 = 6×18×2.1/(5×32) g H2O

= 1.42g H2O
