How to find the formula for the empirical formula?

To do this, you have to find a whole number that can be multiplied by each individual number in your atomic ratio to get a whole number. For example: Try 2. Multiply the numbers in your atomic ratio (1, 1.33, and 1.66) by 2.

How is the empirical formula of glucose determined?

It is determined using data from experiments and therefore empirical. For example, the molecular formula of glucose is C6H12O6 but the empirical formula is CH2O. This is because we can divide each number in C6H12O6 by 6 to make a simpler whole number ratio.

How to find the empirical formula for atomic ratio?

Multiply the numbers in your atomic ratio (1, 1.33, and 1.66) by 2. You get 2, 2.66, and 3.32. These are not whole numbers so 2 doesn’t work. Try 3. You get 3, 4, and 5 when you multiply 1, 1.33, and 1.66 by 3. Therefore, your atomic ratio of whole numbers is 3 : 4 : 5. Understand what those whole numbers mean for the empirical formula.
