What's the difference between structural and molecular formulas?

The molecular formula gives the ratio between these elements. Structural formula gives the relative positions of these atoms. The main difference between molecular formula and structural formula is that molecular formula cannot indicate the relative positions of the atoms whereas structural formula indicates the relative positions of the atoms. 1.

How to find molecular formula from empirical formula?

CH 2 O has one carbon atom (12g), two hydrogen atoms (2g) and one oxygen atom (16g). Its total mass is thus 30 grams. However, the sample weighs 180 grams, which is 180/30 = 6 times as much. You therefore have to multiply the subscript of each element in the formula by 6 to get C 6 H 12 O 6, which is the molecular formula for the compound.

When do you write an empirical formula for a polymer?

When writing empirical formulas for polymers, we write the repeating unit, and then we use the letter “n” to say that there can be n number of repeating units in the polymer. However, we cannot use the empirical formula to find the mass, structure or isomers of a molecule, but it is useful for analytical purposes.

How can you derive the molecular formula of a compound?

You can derive the molecular formula of a compound from its empirical formula only if you know the molar mass of the compound. If you know the empirical formula of a compound, you know the elements present in the compound and their relative proportions.
