1. What is Mole to Gram Conversion?

The mole to gram conversion is a fundamental calculation in chemistry that converts the amount of substance (in moles) to mass (in grams) using the molar mass of the compound or element.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( g \) — Mass in grams (g)
• \( n \) — Amount of substance in moles (mol)
• \( MW \) — Molar mass in grams per mole (g/mol)

Explanation: The formula directly relates the number of particles (moles) to mass through the molar mass, which serves as a conversion factor.

3. Importance of Mole-Gram Conversion

Details: This conversion is essential for laboratory preparations, stoichiometric calculations in chemical reactions, and determining quantities of substances needed for experiments.

4. Using the Calculator

Tips: Enter the amount of substance in moles and the molar mass in g/mol. Both values must be positive numbers. The result will be the mass in grams.

5. Frequently Asked Questions (FAQ)

Q1: Why is molar mass important in this calculation?
A: Molar mass serves as the conversion factor between the number of particles (moles) and mass (grams), as it represents the mass of one mole of a substance.

Q2: Can I use this for any chemical substance?
A: Yes, as long as you know the correct molar mass of the substance (element or compound).

Q3: 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 of ~18.015 g/mol (2×1.008 + 15.999).

Q4: What's the difference between molecular weight and molar mass?
A: They are numerically identical but molecular weight is dimensionless while molar mass has units of g/mol.

Q5: Can this calculator work in reverse (grams to moles)?
A: Not directly, but you can rearrange the formula: n = g/MW.
