Question

How many grams of HNO3 are produced when 55.3 g of H₂O completely reacts?

Express your answer with the appropriate units.

Answer 1

m(HNO3)=193.41g

Step-by-step explanation:

HNO3 + H2O produce H3O+ and NO3+

n(H2O)=m/M= 55.3g/(18g/mol) =3.07mol

n(HNO3)/n(H2O)= x/1

n(HNO3)=3.07mol

Mass of HNO3 is given as m(HNO3)= 3.07mol ×63g/mol= 193.41g.
