Answer:
C2H6O1
Explanation:
Empirical formula means to express the ratio of the number of atoms , i.e to identify which of the three elements appears with the smallest number of atoms in the formula, and then to get the rate of the atoms belonging to other species in respect with this one. In this molecule Oxygen shows the smallest number of moles (0.0065) (O1)
To see how many moles of carbon correspond to 1 mole of Oxygen, divide 0.013 moles of C to 0.0065 moles of Oxygen: 0.013/0.0065 =2 Therefore for each mole of Oxygen you have two moles of C (C2)
To see how many moles of Hydrogen correspond to 1 mole of Oxygen, divide 0.039 moles of H to 0.0065 moles of Oxygen: 0.039/0.0065 =6 Therefore for each mole of Oxygen you have six moles of H (H6)
The empirical formula is C2H6O1
