1. What Is g/L To mmol/L Conversion?

The g/L to mmol/L conversion is essential in dialysis and medical chemistry to convert mass concentration (grams per liter) to molar concentration (millimoles per liter). This conversion requires knowing the molecular weight of the substance.

2. How Does The Calculator Work?

The calculator uses the following formula:

Where:

• Daily g/L — Concentration in grams per liter
• MW — Molecular weight in grams per mole
• 1000 — Conversion factor from moles to millimoles

Explanation: The formula converts mass concentration to molar concentration by dividing by the molecular weight and scaling to millimoles.

3. Importance Of This Conversion

Details: In dialysis, many solutions are prepared in g/L but need to be administered in mmol/L for proper dosing. This conversion ensures accurate preparation of dialysis solutions.

4. Using The Calculator

Tips: Enter the concentration in g/L and the molecular weight of the substance in g/mol. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is this conversion important in dialysis?
A: Dialysis solutions need precise molar concentrations for effective treatment, while stock solutions are often prepared by weight.

Q2: Where can I find molecular weights of common substances?
A: Molecular weights can be found in chemical reference tables or calculated from the chemical formula (sum of atomic weights).

Q3: What are typical molecular weights for dialysis solutions?
A: For example: NaCl (58.44 g/mol), KCl (74.55 g/mol), CaCl₂ (110.98 g/mol), NaHCO₃ (84.01 g/mol).

Q4: Does temperature affect this conversion?
A: The conversion itself is temperature-independent, but solution preparation may require temperature adjustments.

Q5: Can this calculator be used for other medical applications?
A: Yes, it can be used for any application requiring conversion between mass and molar concentrations.
