Enter the total number of moles and the molar mass of the product (g/mole) into the Theoretical Mass Calculator. The calculator will evaluate and display the Theoretical Mass.

## Theoretical Mass Formula

The following formula is used to calculate the Theoretical Mass.

**TM = #n * mm**

- Where TM is the Theoretical Mass (g)
- #n is the total number of moles
- mm is the molar mass of the product (g/mole)

## How to Calculate Theoretical Mass?

The following example problems outline how to calculate Theoretical Mass.

Example Problem #1:

- First, determine the total number of moles.
- The total number of moles is given as: 5.

- Next, determine the molar mass of the product (g/mole).
- The molar mass of the product (g/mole) is provided as: 70.

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

TM = #n * mm

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

TM = 5 * 70 = 35 (g)

Example Problem #2:** **

For this problem, the variables needed are provided below:

total number of moles = 4

molar mass of the product (g/mole) = 76

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

TM = #n * mm** = ?**
