Moles to Grams Formula:
| From: | To: |
The moles to grams conversion is a fundamental calculation in chemistry that converts the amount of substance (in moles) to its corresponding mass (in grams) using the molar mass of the substance.
The calculator uses the simple formula:
Where:
Explanation: This calculation is based on the definition of a mole, which is the amount of substance that contains as many elementary entities as there are atoms in exactly 12 grams of carbon-12.
Details: This conversion is essential for chemical reactions, stoichiometric calculations, and preparing solutions with precise concentrations in laboratory and industrial settings.
Tips: Enter the amount in moles and the molar mass of the substance in g/mol. Both values must be positive numbers. The molar mass can be found on the periodic table or calculated from the chemical formula.
Q1: What is the difference between moles and grams?
A: Moles measure the number of particles (6.022 × 10²³ particles per mole), while grams measure mass. The conversion connects these two concepts.
Q2: How do I find the molar mass of a compound?
A: Sum the atomic masses of all atoms in the molecule. For example, water (H₂O) has molar mass = 2(1.008) + 15.999 = 18.015 g/mol.
Q3: Can I convert grams to moles with this calculator?
A: This calculator only converts moles to grams. For the reverse calculation, you would divide grams by molar mass.
Q4: Why is the mole concept important in chemistry?
A: It allows chemists to count particles by weighing them, making it practical to work with the extremely small sizes of atoms and molecules.
Q5: What is Avogadro's number?
A: It's 6.022 × 10²³, the number of particles in one mole of a substance, named after scientist Amedeo Avogadro.
