Question

Acid rain can be destructive to both the natural environment and human-made structures. The equation below shows a reaction that occurs that may lead to the formation of acid rain. 3NO2 + H2O mc025-1.jpg 2HNO3 + NO How many moles (precise to the nearest 0.01 mol) of nitric acid are produced from 300.00 mol of nitrogen dioxide?

Answer 1

The moles of nitric acid formed can be computed using the stoichiometric relation obtained from the given equation which indicates that for every 3 moles of nitrogen dioxide (NO2), 2 moles of nitric acid (HNO3) is formed. 300 moles of NO2 is then multiplied to 2 mol HNO3/ 3 mol NO2. The answer is 200 moles of nitric acid is produced from 300 moles of NO2. 

Answer 2

Answer;

200.00 moles of nitric acid is produced

Explanation;

From the equation;

3NO2 + H2O → 2HNO3 + NO

The mole ratio of nitrogen (IV) oxide  and nitric acid is 3 is to 2;

Thus; for every 3 moles of nitrogen dioxide (NO2), 2 moles of nitric acid (HNO3) are formed. 

Therefore; 300 moles of NO2 will produce;

2 mol HNO3/ 3 mol NO2 (300) = 200 moles

Hence, 200 moles of nitric acid are produced from 300 moles of NO2.
