How are subscripts used in the empirical formula?

Round up to the closest whole number. This is denoted by subscripts in the empirical formula and is the mole ratio of the elements. Multiply each answer by the same factor to get the lowest whole number multiple, if the number is too far to round off (x.1 ~ x.9). e.g. Multiply each solution in the problem by 4 to get 5, if one solution is 1.25.

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. You get 2, 2.66, and 3.32.

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.

Why is the empirical formula for glucose called the simplest?

Also Known As: The empirical formula is also known as the simplest formula because the subscripts are the smallest whole numbers that indicate the ratio of elements. Glucose has a molecular formula of C 6 H 12 O 6. It contains 2 moles of hydrogen for every mole of carbon and oxygen. The empirical formula for glucose is CH 2 O.
