Answer:
Q1: NO
Q2: NO
Explanation:
Step 1: Given data
Percentage by mass of nitrogen: 46.68%
Percentage by mass of oxygen: 53.32%
Step 2: Divide each percentage by the mass of the element
N: 46.68/14.01 = 3.332
O: 53.32/16.00 = 3.332
Step 3: Divide both numbers by the smallest one (in this case is the same)
N: 3.332/3.332 = 1
O: 3.332/3.332 = 1
The empirical formula is NO. Its molar mass is 30.01 g/mol.
Step 4: Calculate "n"
n = molar mass of the molecular formula / molar mass of the empirical formula
n = (30.01 g/mol) / (30.01 g/mol) = 1
Step 5: Determine the molecular formula
We do so by multiplying the empirical formula by "n".
NO × 1 = NO

The respiratory system is responsible for the exchange of oxygen and carbon dioxide. This is the exchange of air in your lungs, to take oxygen in, and to breathe carbon dioxide and other wastes out.
I hope this helps!
