1. What is Concentration from Molarity?

The concentration of a solution is the amount of solute present in a given quantity of solvent or solution. Molarity (M) is the number of moles of solute per liter of solution. This calculator converts molarity to concentration in grams per liter (g/L) using the molecular weight of the solute.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( C \) — Concentration (g/L)
• \( M \) — Molarity (mol/L)
• \( MW \) — Molecular weight (g/mol)

Explanation: The formula multiplies the molarity (moles per liter) by the molecular weight (grams per mole) to get concentration in grams per liter.

3. Importance of Concentration Calculation

Details: Converting between molarity and concentration is essential in chemistry for preparing solutions, performing dilutions, and conducting quantitative analyses.

4. Using the Calculator

Tips: Enter the molarity in mol/L and the molecular weight in g/mol. Both values must be positive numbers. The result will be in g/L.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between molarity and concentration?
A: Molarity is moles per liter, while concentration is grams per liter. They're related through the molecular weight.

Q2: Can I use this for any solute?
A: Yes, as long as you know its molecular weight. Works for single compounds, not mixtures.

Q3: What units does this calculator use?
A: Inputs are in mol/L and g/mol, output is in g/L. For other units, convert first.

Q4: How precise should my molecular weight be?
A: Use at least 2 decimal places for most applications. For very precise work, use more significant figures.

Q5: What if my solute is a hydrate?
A: Include the water molecules in the molecular weight (e.g., for CuSO₄·5H₂O, use 249.69 g/mol not 159.61 g/mol).
