Relevant Equations

I need help with a question

Am I doing this correctly?
Compound 1
Mass percentage of nitrogen 64.17
Atomic mass of nitrogen 14
Compound 1
Mass Percentage of oxygen 35.73
Atomic mass of oxygen 16
Number of moles
64.17/14 = 4.58
35.73/16 = 2.23

Compound 2
Mass percentage of nitrogen 47.23
Atomic mass of nitrogen 14
Compound 2
Mass percentage of oxygen 52.79
Atomic mass of oxygen 16
Number of moles
47.23/14 = 3.37
52.79/16 = 3.29
