Moles to Grams Formula:
| From: | To: |
The moles to grams formula (g = mol × MM) is used to convert the amount of substance in moles to its corresponding mass in grams. This conversion is fundamental in chemistry for quantitative analysis and stoichiometric calculations.
The calculator uses the simple formula:
Where:
Explanation: The formula multiplies the number of moles by the molar mass of the substance to obtain the mass in grams.
Details: Accurate mass calculation from moles is essential for preparing solutions, conducting chemical reactions, and determining yields in laboratory and industrial settings.
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 grams.
Q1: 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 calculated by summing the atomic masses of all atoms in a molecule.
Q2: How do I find the molar mass of a compound?
A: Add the atomic masses of all atoms in the compound. For example, water (H₂O) has a molar mass of (2×1.008) + 16.00 = 18.016 g/mol.
Q3: Can this calculator be used for any substance?
A: Yes, as long as you know the correct molar mass of the substance, this formula works for elements, compounds, and mixtures.
Q4: What's the difference between mass and moles?
A: Mass is a measure of the amount of matter (in grams), while moles count the number of particles (atoms, molecules, ions) in a sample.
Q5: Why is this conversion important in chemistry?
A: It allows chemists to convert between the number of particles (moles) and measurable mass (grams), which is crucial for quantitative chemical analysis and reaction stoichiometry.
