How to fill out empirical and molecular formula

01

To fill out the empirical formula, follow these steps:

02

Write down the elemental composition of the compound in terms of the number of atoms present. For example, if a compound contains 2 hydrogen atoms and 1 oxygen atom, write H2O.

03

Divide all the subscripts in the formula by the greatest common divisor to get the simplest ratio. In the example above, the ratio is 2:1, so the empirical formula is H2O.

04

05

To fill out the molecular formula, you need to know the molar mass of the compound. Here's how:

06

Find the empirical formula of the compound as described above.

07

Calculate the molar mass of the empirical formula by summing up the atomic masses of all the elements in the formula.

08

Divide the molar mass of the compound by the molar mass of the empirical formula to calculate the simplest ratio of the molecular formula.

09

Multiply the subscripts in the empirical formula by this ratio to get the molecular formula.

10

11

For example, if the empirical formula is CH2O and the molar mass is 180 g/mol, divide 180 by the molar mass of CH2O (30 g/mol) to get a ratio of 6. Multiply the subscripts in CH2O by 6 to get the molecular formula C6H12O6.
