Question

Two different compounds are obtained by combining nitrogen with oxygen. the first compound results from combining 46.7 g of n with 53.3 g of o, and the second compound results from combining 17.9 g of n and 82.0 g of o. calculate the ratio of the mass ratio of o to n in the second compound to the mass ratio of o to n in the first compound. express your answer numerically.

Answer 1

First:

46.7 g of N with 53.3 g of O,

=> mass ratio O to N = 53.3 / 46.7 = 1.1413

Second

17.9 g of N and 82.0 g of O.

mass ratio of O to N = 82.0 / 17.9 = 4.5810

Third

Ratio of the mass ratio of O to N in the second compound to the mass ratio of O to N in the first compound =

= 4.5810 / 1.1413 = 4.013 ≈ 4

Answer: 4
