Convert moles to kg

Looking to convert moles to kilograms effortlessly? Our fast and accurate Moles to Kilograms Converter makes it easy to calculate the mass of any substance using its molar mass (g/mol) and the number of moles. Just enter the number of moles, and the tool will instantly give you the equivalent weight in kilograms.

What is a Mole in Chemistry?

In chemistry, a mole represents 6.022 × 10²³ particles of a substance — be it atoms, molecules, or ions. It’s a standard unit used to express the amount of a chemical substance.

But how do you go from moles to mass in kilograms? That’s where this tool comes in.

How to Convert Moles to Kilograms

To convert moles to kilograms, you need:

• The number of moles
• The molar mass of the substance in g/mol

Formula:

Mass (kg) = Moles × Molar Mass (g/mol) ÷ 1000

This tool uses the exact formula and gives instant results.

How to Use the Converter

Let’s say you want to convert 2 moles of water (H₂O) to kilograms. The molar mass of water is 18.015 g/mol.

1. Enter 2 in the “Moles” field.
2. Enter 18.015 in the “Molar Mass” field.
3. Hit “Convert”.

The result: 0.036030 kg

Is 1 mole equal to 1 kg?

No, 1 mole is not always equal to 1 kilogram.

A mole measures quantity (the number of particles), while a kilogram measures mass. The mass of 1 mole of a substance depends entirely on its molar mass (g/mol). For example:

• 1 mole of water (H₂O) weighs 18.015 grams (or 0.018015 kg).
• 1 mole of sodium chloride (NaCl) weighs 58.44 grams (or 0.05844 kg).
• 1 mole of glucose (C₆H₁₂O₆) weighs 180.16 grams (or 0.18016 kg).

So, 1 mole equals 1 kg only if the substance’s molar mass is 1000 g/mol, which is extremely rare.

How many kg is one mole?

To determine how many kilograms are in one mole, you need the molar mass of the substance (in grams per mole).

Use this formula:

Mass (kg) = Molar Mass (g/mol) ÷ 1000

Examples:

• 1 mole of water (H₂O):
  18.015 ÷ 1000 = 0.018015 kg
• 1 mole of CO₂:
  44.01 ÷ 1000 = 0.04401 kg

So the kg value varies depending on the compound.

How many moles are in a kilogram?

To find out how many moles are in 1 kilogram of a substance, use this formula:

Moles = 1000 ÷ Molar Mass (g/mol)

Examples:

• Water (H₂O):
  1000 ÷ 18.015 = ~55.5 moles
• CO₂:
  1000 ÷ 44.01 = ~22.7 moles

So, the number of moles in 1 kg depends on the molar mass of the substance.
