To calculate the number of moles from volume:
\[ n = M \cdot V \]
Where:
Converting mL to moles is done through the multiplication of molarity and volume. Molarity is a measure of the number of moles per unit of volume.
Let's assume the following values:
Using the formula:
\[ n = 5 \cdot 10 = 50 \]
The number of moles is 50.
