That’s where the Mol To Grams Calculator comes in. This free, easy-to-use online tool helps you quickly convert the number of moles of a substance into grams by applying the fundamental formula:

Grams = Moles × Molar Mass

Whether you are a student solving homework problems, a lab technician preparing solutions, or a researcher handling experimental data, this calculator saves time and ensures precision.

How to Use the Mol To Grams Calculator (Step-by-Step)

Using the calculator is simple and straightforward. Here’s a step-by-step guide:

1. Enter Moles (mol):
   • Type in the amount of substance in moles that you want to convert.
   • Example: 2 mol.
2. Enter Molar Mass (g/mol):
   • Input the molar mass of the compound. This is usually found on the periodic table or chemical references.
   • Example: Water (H₂O) has a molar mass of 18.015 g/mol.
3. Optional – Compound Name:
   • For clarity, you can enter the name of the compound (e.g., Water, NaCl, Glucose).
4. Click “Calculate”:
   • The calculator will process the values and display the total grams along with detailed results.
5. Reset or Start Again:
   • Use the Reset button to clear inputs and begin a new calculation.
6. Copy or Share Results:
   • You can copy the results to your clipboard or share them directly.

Practical Example

Let’s walk through an example with Water (H₂O):

• Step 1: Enter moles = 2 mol
• Step 2: Enter molar mass = 18.015 g/mol
• Step 3: Click Calculate

Result:
2 mol × 18.015 g/mol = 36.03 g

This means that 2 moles of water equal 36.03 grams.
