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: The molar mass acts as a conversion factor between the number of particles (moles) and mass (grams).
Details: This conversion is essential for laboratory preparations, chemical reactions, stoichiometric calculations, and determining exact quantities of substances needed for experiments.
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 a mole in chemistry?
A: A mole is the SI unit for amount of substance, representing exactly 6.02214076×10²³ particles (Avogadro's number).
Q2: How do I find molar mass?
A: Molar mass is the sum of atomic masses of all atoms in a molecule. For elements, it's the atomic weight from the periodic table.
Q3: Can I convert grams to moles with this?
A: The reverse calculation (grams to moles) would use the formula: moles = grams / molar mass.
Q4: Why is molar mass important?
A: Molar mass allows chemists to work between the microscopic scale (number of atoms/molecules) and macroscopic scale (measurable mass).
Q5: What's the difference between molecular weight and molar mass?
A: Molecular weight is dimensionless, while molar mass has units of g/mol, but numerically they're often the same.
