1. What is the Mole To Kg Formula?

The Mole To Kg formula converts the amount of substance in moles to mass in kilograms using the molar mass of the substance. This conversion is fundamental in chemistry for quantifying chemical substances.

2. How Does the Calculator Work?

The calculator uses the Mole To Kg formula:

Where:

• \( moles \) — Amount of substance in moles (mol)
• \( Molar Mass \) — Molar mass of the substance (g/mol)
• \( 1000 \) — Conversion factor from grams to kilograms

Explanation: The formula multiplies the number of moles by the molar mass to get mass in grams, then divides by 1000 to convert to kilograms.

3. Importance of Mass Calculation

Details: Accurate mass calculation from moles is essential for chemical reactions, stoichiometry, solution preparation, and various laboratory measurements in chemistry.

4. Using the Calculator

Tips: Enter the amount in moles and the molar mass in g/mol. Both values must be positive numbers. The result will be displayed in kilograms.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 1000 in the formula?
A: The division by 1000 converts the mass from grams (g) to kilograms (kg), as 1 kg = 1000 g.

Q2: What is molar mass?
A: Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It can be found by summing the atomic masses of all atoms in a molecule.

Q3: Can this calculator be used for any chemical substance?
A: Yes, as long as you know the correct molar mass of the substance, this calculator can be used for any chemical compound or element.

Q4: What are typical molar mass values?
A: Molar mass values vary widely. For example: Water (H₂O) = 18.015 g/mol, Sodium chloride (NaCl) = 58.44 g/mol, Glucose (C₆H₁₂O₆) = 180.16 g/mol.

Q5: How precise should the inputs be?
A: The precision depends on your application. For most laboratory work, 4 significant figures are sufficient, but research may require higher precision.
