Step 1I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2: Understanding the Basic Relationship
\text{Molarity} = \frac{\text{moles of solute}}{\text{liters of solution}}
Molarity (M) is defined as the number of moles of solute per liter of solution:
Final Answer
Millimoles (mmol) can be calculated from molarity and volume using the same mathematical relationship as mol/L. The units are directly convertible due to the 1000:1 conversion factor between mol and mmol, and L and mL. Therefore, molarity expressed as mol/L is numerically identical to concentration expressed as mmol/mL.
