Yes, the empirical formula can be used to determine the percent composition of a compound. The percent composition can be calculated by determining the molar mass of each element in the formula and then dividing the molar mass of each element by the molar mass of the whole compound, and finally multiplying by 100 to get the percent composition.
The percent composition only tells us the relative proportions of the elements present in the compound, not the specific arrangement of atoms within the molecule. Different compounds can have the same percent composition but different structures, leading to different molecular formulas. For example, both ethanol (C2H6O) and dimethyl ether (C2H6O) have the same percent composition, but are different compounds with distinct structures.
The empirical formula of the compound with 52.7% K and 47.3% Cl is KCl (potassium chloride). This is because the ratio of potassium to chlorine atoms in the compound is 1:1, leading to the simple formula KCl.
The empirical formula is CH2O. To find the molecular formula, you need to calculate the empirical formula weight (30 g/mol) and divide the molecular mass (180.0 g/mol) by the empirical formula weight to get 6. This means the molecular formula is (CH2O)6, which simplifies to C6H12O6, the molecular formula of glucose.
- The percent composition of a compound is established after the chemical analysis of this compound and the knowledge of the chemical formula.- If you know the chemical formula you need to know the atomic weights of the components to calculate the percent composition.
The percent composition of a compound with the empirical formula CO2 is 27.3% carbon and 72.7% oxygen.
You should solve for an empirical formula when you are given the percent composition of elements in a compound or when you have the molar mass of the compound but not the molecular formula. The empirical formula provides the simplest whole-number ratio of atoms in a compound.
Percent composition can be used to calculate the percentage of an element/compound in a mixture. From the percent composition, you can also find the empirical formula. And from the empirical formula you can find the actual molecular weight.

The empirical formula of this compound would be MgO.
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
