The Empirical formula of an organic compound is= C_3H_6O_2

Explanation:

Mass of an organic compound = 200 g

Mass of carbon = 97.30 g

moles of carbon = $\frac{97.30 g}{12 g/mol}=8.108 mol$

Mass of hydrogen = 16.22 g

Moles of hydrogen = $\frac{16.22 g}{1 g/mol}=16.220 mol$

Mass of oxygen = 200 g - 97.30 g - 16.22 g = 86.48 g

Moles of oxygen = $\frac{86.48 g}{16 g/mol}=5.405 mol$

Divide the all the moles of element with smallest value of moles.

Carbon = $\frac{8.108 mol}{5.405 mol}=1.5$

Hydrogen = $\frac{16.220 mol}{5.405 mol}=3$

Oxygen = $\frac{5.405 mol}{5.405 mol}=1$

Empirical formula = $C_{1.5}H_3O_1$

Converting them into whole number ratios.

Empirical formula = C_3H_6O_2

As pieces of once living things, body fossils are evidence of what was living where and when. Trace fossils are valuable because they "animate" the ancient animals or plants by recording a moment of an organism's life when it was still alive.
