1. What is mg/mL to mmol/L Conversion?

The mg/mL to mmol/L conversion is used to convert mass concentration to molar concentration. This is essential in chemistry and biochemistry where reactions depend on the number of molecules (moles) rather than mass.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( \text{mg/mL} \) — Mass concentration in milligrams per milliliter
• \( \text{MW} \) — Molecular weight in grams per mole
• \( \text{mmol/L} \) — Molar concentration in millimoles per liter

Explanation: The formula converts mass to moles using the molecular weight, and adjusts units from mg to g (×1000) and mL to L (implicit in the conversion).

3. Importance of Unit Conversion

Details: Accurate unit conversion is crucial for preparing solutions, calculating reaction stoichiometry, and comparing concentrations across different compounds.

4. Using the Calculator

Tips: Enter concentration in mg/mL and molecular weight in g/mol. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 1000 in the formula?
A: We multiply by 1000 to convert mg to g (1 g = 1000 mg) since molecular weight is in g/mol.

Q2: How do I find molecular weight?
A: Molecular weight is the sum of atomic weights of all atoms in the molecule, available in chemical databases or periodic tables.

Q3: Can I use this for mixtures?
A: No, this calculator is for pure compounds. For mixtures, you need the concentration of each component separately.

Q4: What's the difference between mmol and mol?
A: 1 mole = 1000 millimoles. mmol is often used for biological concentrations which are typically small.

Q5: How precise should my molecular weight be?
A: Use at least 2 decimal places for most applications. For very precise work, use more decimal places.
