Using this tool is simple and requires only a few steps:

Step 1: Enter Input Value

Input the value you want to convert. This could be grams, moles, or number of molecules depending on your selected conversion type.

Step 2: Enter Molar Mass (if required)

For conversions involving grams and moles, you must enter the molar mass in g/mol.

Step 3: Choose Conversion Type

Select one of the following options:

Grams to Moles
Moles to Grams
Molecules to Moles
Moles to Molecules

Step 4: Click “Calculate”

The calculator instantly displays the result along with the appropriate unit.

Step 5: Reset for New Calculation

Click the reset button to clear inputs and start again.

Formulas Used in the Calculator

The calculator uses standard chemistry formulas:

1. Grams to Moles

n = m ÷ M

2. Moles to Grams

m = n × M

3. Molecules to Moles

n = N ÷ NA

4. Moles to Molecules

N = n × NA

Where:

n = moles
m = mass (grams)
M = molar mass
N = number of molecules
NA = Avogadro’s number (6.022 × 10²³)

Example Calculations

Example 1: Grams to Moles

Mass = 20 g
Molar Mass = 40 g/mol

Calculation:
n = 20 ÷ 40 = 0.500 mol

Example 2: Moles to Grams

Moles = 3 mol
Molar Mass = 18 g/mol

Calculation:
m = 3 × 18 = 54 g

Example 3: Molecules to Moles

Molecules = 3.011 × 10²³

Calculation:
n = (3.011 × 10²³) ÷ (6.022 × 10²³) = 0.500 mol

Example 4: Moles to Molecules

Moles = 2 mol

Calculation:
N = 2 × 6.022 × 10²³ = 1.204 × 10²⁴ molecules

Key Features of This Tool

Supports four essential mole conversions
Handles large and small numbers with scientific notation
Instant and accurate results
Clean, responsive interface
No technical knowledge required
