Answer: 17.03 g/mol
Explanation: The molar mass of ammonia (NH\(_3\)) is calculated by adding the atomic masses of nitrogen (N) and hydrogen (H). Nitrogen has an atomic mass of approximately 14.01 g/mol, and hydrogen has an atomic mass of about 1.01 g/mol. Since there are three hydrogen atoms in ammonia, the calculation is as follows:
\[
\text{Molar mass of NH}_3 = 14.01 \, \text{g/mol} + (3 \times 1.01 \, \text{g/mol}) = 14.01 \, \text{g/mol} + 3.03 \, \text{g/mol} = 17.04 \, \text{g/mol}
\]
Rounding gives us 17.03 g/mol.
