Enter the number of moles of element (moles) and the smallest number of moles (moles) into the Mole to Mole Ratio Calculator. The calculator will evaluate and display the Mole to Mole Ratio.

## Mole to Mole Ratio Formula

The following formula is used to calculate the Mole to Mole Ratio.

MMR = NE / SN
• Where MMR is the Mole to Mole Ratio (mole/mole)
• NE is the number of moles of element (moles)
• SN is the number of smallest number of moles (moles)

To calculate a mole ratio, divide the number of moles of the element by the number of moles in the element with the smallest number of moles.

## How to Calculate Mole to Mole Ratio?

The following example problems outline how to calculate Mole to Mole Ratio.

Example Problem #1:

1. First, determine the number of moles of element (moles).
• The number of moles of element (moles) is given as: 12.
2. Next, determine the number of smallest number of moles (moles).
• The number of smallest number of moles (moles) is provided as: 10.
3. Finally, calculate the Mole to Mole Ratio using the equation above:

MMR = #NE / #SN

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

MMR = 12 / 10 = 1.2 (mole/mole)

Example Problem #2:

For this problem, the variables required are provided below:

number of moles of element (moles) = 13

number of smallest number of moles (moles) = 5

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

MMR = #NE / #SN = ?
