Step-by-step explanation:
Percentage by mass of Nitrogen: 47%
Molar mass of Nitrogen: 14
Portion of moles of Nitrogen: 47/14 = 3.36
Percentage by mass of Oxygen: 53%
Molar mass of Oxygen: 16
Portion of moles of Oxygen: 53/16 = 3.31
3.36 : 3.31 is approximately 1 : 1 so the empirical formula is:
A. NO
