QUESTION:

Nitrogen dioxide and water react to produce nitric acid, HNO3, and nitrogen oxide.3NO2(g) + H2O(l) ? 2HNO3(aq) + NO(g)a. How many grams of H2O are required to react with 28.0 g of NO2?b. How many grams of NO are produced from 15.8 g of H2O?c. How many grams of HNO3 are produced from 8.25 g of NO2?

ANSWER:

Solution 55 QP: Step 1: (a)Here, we are going to find out the amount of of H2O are required to react with 28.0 g of NO2We know3NO2(g) + H2O(l) 2HNO3(aq) + NO(g)The molar mass of NO2 = 46 g/molMass given = 28.0 gThe amount of NO2 = 1/ 46 g/mol 28.0 g = 0.609 moleThus, = H2OWe know thatThe molar mass of H2O =18.02 g/molTherefore, the amount of H2O are required to react with 28.0 g of NO2= 18.02 g/mol = 3.656 gThus, 3.656 g of H2O are required to react with 28.0 g of NO2________________
