Answer to Question #172091 in General Chemistry for s_l

Question

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?

Answer 1

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
