Which is the correct statement about one mole of ammonia, NH₃?

Question

Quizplus · Accepted Answer

A) One mole of ammonia contains one mole of nitrogen and three moles of hydrogen. The molar mass of nitrogen is 14 g/mol, and the molar mass of hydrogen is 1 g/mol, so one mole of ammonia contains 14 + 3 = 17 g/mol.
B) Avogadro's number, 6.02 × 10^23, is defined as the number of particles in one mole of a substance. Therefore, one mole of ammonia contains 6.02 × 10^23 molecules.
C) One mole of ammonia contains three moles of hydrogen, and one mole of hydrogen contains 6.02 × 10^23 atoms. Therefore, one mole of ammonia contains 3 × 6.02 × 10^23 = 1.8 × 10^24 atoms of hydrogen.
