What is the molecular weight of Ammonia (NH3) ________ ?
Correct answer: A. 17.031 g/mol
- A. 17.031 g/mol
- B. 18.031 g/mol
- C. 19.031 g/mol
- D. 27.033 g/mol
Explanation
Ammonia has one nitrogen atom and three hydrogen atoms, so its molar mass is about 14.01 + 3(1.008) = 17.03 g/mol. Therefore 17.031 g/mol is the matching value.
