## Average Mass Formula

The following formula is used to calculate the Average Mass.

AM = (M1+M2+M3)/ 3

- Where AM is the Average Mass (kg)
- M1 is the mass of object 1 (kg)
- M2 is the mass of object 2 (kg)
- M3 is the mass of object 3 (kg)

To calculate an average mass, sum the all of the masses together, then divide by the number of individual masses.

## How to Calculate Average Mass?

The following example problems outline how to calculate Average Mass.

**Example Problem #1**

- First, determine the mass of object 1 (kg).
- The mass of object 1 (kg) is calculated to be : 14.

- Next, determine the mass of object 2 (kg).
- The mass of object 2 (kg) is measured to be: 70.

- Next, determine the mass of object 3 (kg).
- The mass of object 3 (kg) is found to be: 50.

- Finally, calculate the Average Mass using the formula above:

AM = (M1+M2+M3)/ 3

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

AM = (14+70+50)/ 3 = 44.66 (kg)

**Example Problem #2**

The variables needed for this problem are provided below:

mass of object 1 (kg) = 8

mass of object 2 (kg) = 90

mass of object 3 (kg) = 10

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

AM = (M1+M2+M3)/ 3 =** **(kg)
