Enter the mass of the sample and the molar mass of the substance into the calculator to determine the number of moles. This calculator can also evaluate any of the variables given the others are known.

## Molar Mass To Moles Formula

The following formula is used to calculate the number of moles from the molar mass.

n = m / M

Variables:

- n is the number of moles
- m is the mass of the sample (g)
- M is the molar mass of the substance (g/mol)

To calculate the number of moles, divide the mass of the sample by the molar mass of the substance. This will give you the number of moles present in the sample. This conversion is crucial in stoichiometry, which involves calculating the relative quantities of reactants and products in chemical reactions.

## What is Molar Mass To Moles?

Molar mass to moles is a conversion process used in chemistry to determine the number of moles in a sample given its mass. The molar mass of a substance is the mass of one mole of that substance, expressed in grams per mole (g/mol). By dividing the mass of the sample by the molar mass of the substance, you can calculate the number of moles present in the sample. This conversion is fundamental in stoichiometry, which is the calculation of relative quantities of reactants and products in chemical reactions.

## How to Calculate Molar Mass To Moles?

The following steps outline how to calculate the Molar Mass To Moles.

- First, determine the mass of the sample (m) in grams.
- Next, determine the molar mass of the substance (M) in grams per mole.
- Next, gather the formula from above: n = m / M.
- Finally, calculate the number of moles (n).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

mass of the sample (m) = 25 g

molar mass of the substance (M) = 50 g/mol
