What is the percentage of nitrogen in NH3NO3?
Correct answer: B. 35%
- A. 65%
- B. 35%
- C. 20%
- D. 58%
Explanation
Mass of N is 14, in NH3NO3 there are two Nitrogens hence the mass of N is 28g.Mass of NH3NO3 = 14+(1x3)+14+(16x3)=79Percentage of N = 28/79 = 35%

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
