Conversion Formula:
| From: | To: |
The mol to g conversion calculates the mass of a substance from its amount in moles and molar mass. This fundamental chemistry calculation is essential for laboratory work, chemical reactions, and stoichiometry.
The calculator uses the conversion formula:
Where:
Explanation: The formula directly converts between moles and grams using the molar mass as the conversion factor, which represents the mass of one mole of a substance.
Details: Accurate mass calculation is crucial for preparing chemical solutions, conducting experiments, calculating reaction yields, and ensuring proper stoichiometric ratios in chemical reactions.
Tips: Enter the amount of substance in moles and the molar mass in g/mol. Both values must be positive numbers. The calculator will provide the mass in grams.
Q1: What is a mole in chemistry?
A: A mole is the SI unit for amount of substance, defined as exactly 6.02214076×10²³ particles (atoms, molecules, ions, etc.).
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 the chemical formula. For example, water (H₂O) has a molar mass of 18.015 g/mol.
Q3: Can this calculator handle decimal values?
A: Yes, the calculator accepts decimal values for both moles and molar mass, providing precise mass calculations.
Q4: What's the difference between molecular weight and molar mass?
A: Molecular weight is the mass of one molecule, while molar mass is the mass of one mole of substance. They have the same numerical value but different units (amu vs g/mol).
Q5: Why is this conversion important in chemistry?
A: This conversion is fundamental for quantitative chemical analysis, reaction stoichiometry, and preparing solutions with precise concentrations.
