Question

a compound contains only nitrogen and oxygen and has a formula mass of 44.02 amu. part a what is its molecular formula? express your answer as a chemical formula. a chemical reaction does not occur for this question. submit request answer provide feedback

Explanation:

Step1: Recall atomic masses

Atomic mass of N: \(14.01\) amu, O: \(16.00\) amu.

Step2: Test possible N-O combinations

• \(N_2O\): \(2\times14.01 + 16.00 = 28.02 + 16.00 = 44.02\) amu.
• Check other ratios (e.g., \(NO\): \(14.01 + 16.00 = 30.01\) amu; \(NO_2\): \(14.01 + 2\times16.00 = 46.01\) amu) don't match.

Answer:

\(N_2O\)
