Mass to Moles Calculator

Formula

The formula to convert mass to moles is:

$n = \frac{m}{M}$

Where:

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

What is Molar Mass?

Molar mass is the mass of one mole of a substance and is expressed in grams per mole (g/mol). It is equivalent to the molecular weight of a substance, where each atomic mass unit (amu) is equal to 1 g/mol. The molar mass is used to convert between the mass of a substance and the amount in moles, which is a fundamental concept in chemistry for stoichiometric calculations.

Example Calculation

Let's assume the following values:

Mass (m): 10 grams
Molar Mass (M): 2 g/mol

Using the formula to convert mass to moles:

$n = \frac{10}{2} = 5 \text{ mol}$

The number of moles is 5 mol.
