According to the law of conservation of mass, if 32.7 grams of N2 and 37.3 grams of O2 combine to form NO, how many grams of NO must form?

Question

The compound NO can be formed by combining N₂ and O₂. This can be represented at the atomic level by a chemical equation:

1. N₂ + O₂  2NO

According to the law of conservation of mass, if 32.7 grams of N₂ and 37.3 grams of O₂ combine to form NO, how many grams of NO must form?

Answer 1

N₂ + O₂ ==> 2NO

32.7....37.3........?.........

According the law of conservation of matter, the mass of the reactants must equal the mass of the products. So, in this case the mass of the product (NO) would have to be ...

32.7 g + 37.3 g = 70.0 g
