Moles Calculator

Formula

The formula to calculate the total number of moles of a substance is:

\[ m = \frac{M}{MW} \]

Where:

\( m \) is the number of moles
\( M \) is the mass (grams)
\( MW \) is the molecular weight (grams/mole)

Mol Definition

A mole is a unitless measure that describes the number of atoms in a particular amount of substance. One mole of any substance contains \(6.022 \times 10^{23}\) entities (atoms, molecules, etc.), known as Avogadro's number.

Example Calculation

Let's assume the following values:

Mass (M): 100 grams
Molecular Weight (MW): 50 grams/mole

Step 1: Calculate the Number of Moles (m):

\[ m = \frac{100}{50} = 2 \text{ moles} \]

The number of moles is 2 moles.
