1. What is M to mg/mL Conversion?

The conversion between molarity (M, mol/L) and mass concentration (mg/mL) is essential in chemistry and biochemistry. It allows researchers to switch between these two common concentration units based on the molecular weight of the substance.

2. How Does the Calculator Work?

The calculator uses the simple formula:

\[ \text{mg/mL} = \text{M} \times \text{MW} \]

Where:

\( \text{M} \) — Molar concentration (moles per liter)
\( \text{MW} \) — Molecular weight (grams per mole)
\( \text{mg/mL} \) — Mass concentration (milligrams per milliliter)

Explanation: Since 1 mole of substance equals its molecular weight in grams, and there are 1000 mg in 1 g and 1000 mL in 1 L, the conversion simplifies to this direct multiplication.

3. Importance of Concentration Conversion

Details: Many laboratory protocols specify concentrations in molarity, while practical measurements often use mass concentration. This conversion is crucial for accurate solution preparation and experimental reproducibility.

4. Using the Calculator

Tips: Enter the molar concentration in mol/L and the molecular weight in g/mol. Both values must be positive numbers. The result will be displayed in mg/mL.

5. Frequently Asked Questions (FAQ)

Q1: Why is molecular weight important in this conversion?
A: Molecular weight provides the link between moles (counting molecules) and mass (weighing substance). Different substances have different molecular weights, so the same molar concentration will yield different mass concentrations.

Q2: Can I convert mg/mL back to M?
A: Yes, by rearranging the formula: \( \text{M} = \frac{\text{mg/mL}}{\text{MW}} \).

Q3: What if my molecular weight is in kDa?
A: 1 kDa = 1000 g/mol. Convert kDa to g/mol before using the calculator.

Q4: Does temperature affect this conversion?
A: The conversion is temperature-independent as it's based on mass and molecular count, not volume changes with temperature.

Q5: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of your molarity and molecular weight values.
