The formula to convert milliliters to millimoles is:
\[ \text{mmol} = \text{Volume (ml)} \times \text{Molarity (M)} \]
Where:
Molarity is a measure of the concentration of a solute in a solution, or of any chemical species, in terms of the amount of substance in a given volume. It is commonly expressed in moles per liter (mol/L). Molarity is used in chemistry to express the concentration of chemical substances.
To calculate molarity, divide the number of moles of solute by the volume of the solution in liters.
Let's consider an example:
Using the formula to calculate the millimoles:
\[ \text{mmol} = 50 \times 0.2 = 10 \, \text{mmol} \]
This demonstrates that with a volume of 50 ml and a molarity of 0.2 mol/L, the solution contains 10 millimoles.
