This measurement provides valuable information about the concentration of a solution, enabling researchers and practitioners to determine its reactivity, stoichiometry, and potential applications.
The volume of 24.68 mL represents a precise quantity of the solution, while the molarity of 0.1165 M indicates the number of moles of solute dissolved per liter of the solution. Understanding the significance of these values is crucial for accurate experimentation and interpretation of chemical reactions.
Understanding the Measurement
The volume measurement of 24.68 ml is a precise and accurate determination of the volume of the prepared solution. It represents the amount of liquid that has been accurately dispensed and is essential for ensuring the desired concentration and consistency of the solution.
Units
The unit used, milliliters (ml), is a metric unit of volume commonly employed in laboratory and scientific settings. One milliliter is equivalent to one cubic centimeter (1 ml = 1 cm³). This unit provides a precise and convenient means of measuring small volumes of liquids, making it particularly suitable for preparing and dispensing solutions.
Concentration and Molarity
Concentration is a measure of the amount of solute present in a given volume of solution. Molarity is a specific unit of concentration that expresses the number of moles of solute per liter of solution. It is a common way to express the concentration of solutions in chemistry.
Calculating Molarity
To calculate the molarity of a solution, we use the following formula:
Molarity (M) = Moles of solute / Volume of solution (in liters)
In this case, we have 24.68 mL of a 0.1165 M solution. To convert mL to L, we divide by 1000:
Volume of solution = 24.68 mL / 1000 mL/L = 0.02468 L
Now we can calculate the molarity:
Molarity = 0.1165 M = 0.1165 moles / 0.02468 L = 4.72 M
Therefore, the molarity of the solution is 4.72 M.
Implications of Molarity
Molarity is a useful measure of concentration because it allows us to easily compare the concentrations of different solutions. It is also used to calculate the amount of solute or solvent needed to prepare a solution of a specific concentration.
For example, if we want to prepare 100 mL of a 1 M solution of NaCl, we would need:
Moles of NaCl = Molarity × Volume of solution (in liters) = 1 M × 0.1 L = 0.1 moles
We can then use the molar mass of NaCl (58.44 g/mol) to calculate the mass of NaCl needed:
Mass of NaCl = Moles of NaCl × Molar mass = 0.1 moles × 58.44 g/mol = 5.844 g
Therefore, we would need to dissolve 5.844 g of NaCl in 100 mL of water to prepare a 1 M solution.
