SUMMARY

This discussion focuses on calculating the mass percentages and number of moles of nitrogen and oxygen in two chemical compounds. For Compound 1, the mass percentage of nitrogen is 64.17% with an atomic mass of 14, resulting in 4.58 moles, while the mass percentage of oxygen is 35.73% with an atomic mass of 16, yielding 2.23 moles. For Compound 2, the mass percentage of nitrogen is 47.23% (3.37 moles) and oxygen is 52.79% (3.29 moles). The calculations are confirmed as accurate based on the provided atomic masses.

PREREQUISITES
  • Understanding of mass percentage calculations
  • Knowledge of atomic mass values for nitrogen and oxygen
  • Familiarity with mole concept in chemistry
  • Basic arithmetic skills for division
