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