# Can empirical formula be the same as the molecular formula?

###### Wiki User

An empirical formula may or may not be the same as a molecular formula. The empirical formula of a compound shows the smallest whole-number ratio of the atoms compound. The molecular formula tells the actual number of each kind of atom present in a molecule of the compound.

### Is the CCL4 empirical formula or molecular formula?

CCl4 is the molecular formula for carbon tetrachloride. It is the same as its empirical formula.

### What is the molecular formula of a compound that has a molecular mass of 46 and an empirical formula of No2?

The molecular formula is the same as the empirical formula, NO2. The compound NO2 has a molar mass of 46g/mol, so the empirical and molecular formulas are the same.

### Can an empirical formula be triple its molecular formula?

Yes, it is possible for an empirical formula to be the same as the molecular formula. For example, Lactic acid's molecular formula is C3H6O3, which would make its empirical formula CH2O.

### How are the empirical and molecular formulas for a compound related?

A molecular formula is identical to the empirical formula, and is based on quantity of atoms of each type in the compound.The relationship between empirical and molecular formula is that the empirical formula is the simplest formula, and the molecular can be the same as the empirical, or some multiple of it. An example might be an empirical formula of C3H8. Its molecular formula may be C3H8 , C6H16, C9H24, etc. Looking at it the other way, if the molecular formula is C6H12O6, the empirical formula would be CH2O.

### How is molecular formula C3H6 and molecular formula C6H12 related?

Both formulas are possible molecular formulas for the same empirical formula, CH2.

### Can the empirical formula of a compound be triple its molecular formula?

No: The molecular formula is never smaller than the empirical formula.

### How do you determine the molecular formula given the empirical formula?

Calculate the empirical formula weight. Find the ratio of the molecular weight to the empirical formula weight. (n= molecular weight/ empirical formular weight). Multiply each subscript of the empirical formula by n.

### How do you calculate Molecular formula from empirical formulaWhat could you do with that information to determine that the empirical and molecular formulas are related to one another by a factor of 6?

In order to find molecular formula from empirical formula, one needs to know the molar mass of the molecular formula. Then you simply divide the molar mass of the molecular formula by the molar mass of the empirical formula to find out how many empirical formulae are in the molecular formula. Then you multiply the subscripts in the empirical formula by that number.
