The formula to calculate grams from mmol is:
\[ G = \frac{mmol \times mol}{1000} \]
where \( G \) is the grams from mmol (grams), \( mmol \) is the millimoles, and \( mol \) is the moles.
To calculate grams from mmol, you multiply the millimoles by the number of moles, then divide by 1000. This conversion is useful in chemistry and biochemistry for determining the mass of a substance from its amount in millimoles.
Let's assume we have the following values:
Step 1: Multiply the mmol by the number of moles:
\[ mmol \times mol = 500 \times 18 = 9000 \]
Step 2: Divide by 1000:
\[ G = \frac{9000}{1000} = 9 \]
Therefore, the Grams from mmol is \( G = 9 \text{ grams} \).
