1. What is Molarity to g/mL Conversion?

The Molarity to g/mL conversion is a fundamental calculation in chemistry that converts the molar concentration of a solution (moles per liter) to mass concentration (grams per milliliter). This is particularly useful when preparing solutions or comparing concentrations in different units.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{g/mL} = \frac{M \times MW}{1000} \]

Where:

Explanation: The formula converts moles per liter to grams per milliliter by multiplying the molarity by the molecular weight (to get grams per liter) and then dividing by 1000 (to convert to grams per milliliter).

3. Importance of Concentration Conversion

Details: Converting between molarity and mass concentration is essential for solution preparation, chemical reactions, and comparing experimental results. Different applications may require different concentration units.

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 displayed in g/mL with 6 decimal places precision.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 1000 in the formula?
A: Because there are 1000 milliliters in 1 liter, so we divide by 1000 to convert from g/L to g/mL.

Q2: Can I use this for any chemical compound?
A: Yes, as long as you know the exact molecular weight of the compound.

Q3: What's the difference between molarity and molality?
A: Molarity is moles per liter of solution, while molality is moles per kilogram of solvent. They're different concentration measures.

Q4: How precise should my molecular weight be?
A: Use the most precise molecular weight available, especially for precise solution preparation.

Q5: Can I convert back from g/mL to molarity?
A: Yes, by rearranging the formula: \( M = \frac{\text{g/mL} \times 1000}{MW} \).
