Question

Laughing gas, N2O, also known as nitrous oxide contains 28.01 g of nitrogen in every 44.01 g of nitrous oxide. What mass of nitrous oxide can be formed from 85.20 g of nitrogen?

Answer 1

Answer : The mass of nitrous oxide formed from 85.20 g of nitrogen is, 133.9 grams.

Explanation :

As we are given that, 28.01 g of nitrogen is present in 44.01 g of nitrous oxide. Now we have to determine the mass of nitrous oxide formed from 85.20 g of nitrogen.

As, 28.01 g of nitrogen is present in 44.01 g of nitrous oxide

So, 85.20 g of nitrogen is present in $\frac{85.20}{28.01}\times 44.01=133.9g$ of nitrous oxide

Thus, the mass of nitrous oxide formed from 85.20 g of nitrogen is, 133.9 grams.
