## Mass Ratio Formula

The following formula is used to calculate the Mass Ratio.

MAR = ME / MC *100

- Where MAR is the Mass Ratio (%)
- ME is the mass of the element (g/mol)
- MC is the mass of the compound (g/mol)

To calculate a mass ratio, divide the mass of the specific element by the mass of the compound, then multiply by 100.

## How to Calculate Mass Ratio?

The following example problems outline how to calculate Mass Ratio.

Example Problem #1:

- First, determine the mass of the element (g/mol).
- The mass of the element (g/mol) is given as: 3.25.

- Next, determine the mass of the compound (g/mol).
- The mass of the compound (g/mol) is provided as: 4.00.

- Finally, calculate the Mass Ratio using the equation above:

MAR = ME / MC *100

The values given above are inserted into the equation below and the solution is calculated:

MAR = 3.25 / 4 *100 = 81.25 (%)

Example Problem #2:** **

For this problem, the variables required are provided below:

mass of the element (g/mol) = 6

mass of the compound (g/mol) = 7

Test your knowledge using the equation and check your answer with the calculator above.

MAR = ME / MC *100** = ?**
