What mass of nitric acid, in grams, can be made from 113g g of ammonia?

Answer 1

Write and balanced the equation.
Convert 113 g NH3 to mols. mols = grams/molar mass.
Using the coefficients in the balanced equation, convert mols NH3 to mols HNO3.
Now convert mols HNO3 to grams. g = mols x molar mass.
