What is the molar mass of nitric oxide (NO)?

• A. 44.0 g/mol
• B. 32.0 g/mol
• C. 30.0 g/mol
• D. 28.0 g/mol

Answer: (C)

Verified step by step guidance

1. Identify the chemical formula of nitric oxide, which is NO, meaning it contains one nitrogen (N) atom and one oxygen (O) atom.
2. Find the atomic masses of nitrogen and oxygen from the periodic table: nitrogen (N) has an atomic mass of approximately 14.0 g/mol, and oxygen (O) has an atomic mass of approximately 16.0 g/mol.
3. Calculate the molar mass of nitric oxide by adding the atomic masses of nitrogen and oxygen: \(\text{Molar mass of NO} = 14.0\ \text{g/mol} + 16.0\ \text{g/mol}\).
4. Sum the values to get the total molar mass of nitric oxide in g/mol.
5. Compare your calculated molar mass with the given options to identify the correct answer.
