How to Convert mmol to Grams?

To convert mmol (millimoles) to grams, you need the molecular weight (molar mass) of the substance. The formula is:

Grams = mmol × Molecular Weight (g/mol) /1000

1. mmol stands for millimoles, which is one-thousandth of a mole.
2. The molecular weight (or molar mass) of a substance is the weight of one mole of that substance, measured in grams per mole (g/mol).
3. Since there are 1000 millimoles in one mole, dividing the molecular weight by 1000 adjusts for this.

Example 1: Sodium Chloride (NaCl)

• The molar mass of NaCl: 58.44 g/mol
• Amount: 250 mmol

Grams = 250 × 58.44 / 1000 = 14.61 g

So, 250 mmol of NaCl is 14.61 grams.

Example 2: Glucose (C₆H₁₂O₆)

• Molar mass of glucose: 180.16 g/mol
• Amount: 50 mmol

Grams = 50 × 180.16 / 1000 = 9.008 g

Thus, 50 mmol of glucose equals 9.008 grams.

Example 3: Custom Substance

If you have a custom molar mass, say 120 g/mol, and you want to convert 100 mmol:

Grams = 100 × 120 / 1000 = 12 g

100 mmol of a substance with a molar mass of 120 g/mol equals 12 grams.

This is a general formula as long as you know the molar mass!
