How many grams of NO2 are needed to form 100.0g of HNO3?

Answer 1

Step 1) How do you get from NO2 to HNO3? What are your reactants? Write a reaction and balance your equation.

4NO2+2H2O+O2 --> 4HNO3

Step 2) Look at the stoichiometric ratio of the reaction.

100 g of HNO3 x (1 mol of HNO3/63.01 g) x (4mol NO2/4molHNO3)x (46.00 g NO2 /mol NO2) = 73 g
