To determine the empirical formula of a compound, we need to find the simplest whole number ratio of atoms present in the compound. The given molecular formula is C6H12O6.

Step 1: Find the moles of each element in one molecule.

- Moles of C = 6

- Moles of H = 12

- Moles of O = 6

Step 2: Divide the moles of each element by the smallest number of moles. In this case, the smallest number of moles is 6.

- Moles of C = 6 / 6 = 1

- Moles of H = 12 / 6 = 2

- Moles of O = 6 / 6 = 1

Step 3: Write the empirical formula using the simplified ratio of moles.

- Empirical formula = CH2O

Therefore, the empirical formula of a compound with molecular C6H12O6 is CH2O.
