<h3><u>Answer;</u></h3>
Empirical formula = C₂H₃O
Molecular formula = C₁₄H₂₁O₇
<h3><u>Explanation</u>;</h3>
Empirical formula
Moles of; 
Carbon = 55.8 /12 = 4.65 moles 
Hydrogen = 7.04/ 1 = 7.04 moles
Oxygen  = 37.16/ 16 = 2.3225 moles 
We then get the mole ratio;
4.65/2.3225 = 2.0
7.04/2.3225 = 3.0
2.3225/2.3225 = 1.0 
Therefore;
The empirical formula = <u>C₂H₃O</u>
Molecular formula;
(C2H3O)n = 301.35 g
(12 ×2 + 3× 1 + 16×1)n = 301.35
43n = 301.35
   n = 7 
Therefore;
Molecular formula = (C2H3O)7
                              <u> = C₁₄H₂₁O₇</u>

Magents have a North and South magnetic attraction and North and North don't attract South and south don't attract either . Only north and south attract which is when they are facing each other that's why they say opposites attract
