Step 1: Understand the concept of molarity
where $n$ is the number of moles of solute and $V$ is the volume of the solution in liters.
Molarity (M) is a unit of concentration in chemistry, which describes the amount of solute (usually in moles, mol) present in a solution per liter of solution (L). The formula to calculate molarity is as follows:
Step 2: Determine the number of moles of solute $(n)$
where $m$ is the mass of the solute and $M$ is its molar mass.
To determine the number of moles of solute, you need to multiply the mass of the solute (in grams, g) by the reciprocal of its molar mass (in g/mol). The formula is as follows:
Final Answer
To calculate the average molarity, you need to determine the total number of moles of solute and the total volume of the solutions, and then divide the total number of moles by the total volume. Remember to use the correct units and the appropriate number of significant figures when reporting the average molarity.
