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 formula:
Where:
Explanation: This calculation is based on the definition of a mole, where one mole of any substance contains exactly the same number of particles (Avogadro's number) and has a mass equal to its molar mass in grams.
Details: This conversion is essential for chemical reactions, stoichiometry calculations, preparing solutions with specific concentrations, and determining reactant quantities in laboratory experiments and industrial processes.
Tips: Enter the amount in moles and the molar mass of the substance in g/mol. Both values must be positive numbers. The calculator will provide the equivalent mass in grams.
Q1: What is a mole in chemistry?
A: A mole is the SI unit for amount of substance, defined as containing exactly 6.02214076×10²³ particles (atoms, molecules, ions, or other particles).
Q2: How do I find the molar mass of a compound?
A: Molar mass is calculated by summing the atomic masses of all atoms in a molecule. For example, water (H₂O) has a molar mass of 18.015 g/mol.
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 convert moles to grams for any chemical compound or element.
Q4: Why is this conversion important in stoichiometry?
A: Chemical equations give mole ratios, but laboratory work requires mass measurements. This conversion bridges the gap between theoretical mole ratios and practical mass measurements.
Q5: What's the difference between molecular weight and molar mass?
A: Molecular weight is the mass of one molecule (in atomic mass units), while molar mass is the mass of one mole of molecules (in grams per mole). Numerically they are equal but have different units.
