examples of how to calculate malarity and titration calculations
1. Calculating Molarity: Molarity is defined as the number of moles of solute per liter of solution. To calculate molarity, you can use the formula:
Molarity (M) = moles of solute / liters of solution
For example, if you have 0.5 moles of NaCl dissolved in 2 liters of solution, the molarity would be:
M = 0.5 moles / 2 L = 0.25 M
2. Titration Calculations: Titration is a technique used to determine the concentration of a solution by reacting it with a solution of known concentration. To calculate the concentration of an unknown solution using titration, you can use the formula:
M1V1 = M2V2
Where M1 is the concentration of the known solution, V1 is the volume of the known solution used in the titration, M2 is the concentration of the unknown solution, and V2 is the volume of the unknown solution.
For example, if 25 mL of a 0.1 M HCl solution is neutralized by 30 mL of a NaOH solution, you can calculate the concentration of the NaOH solution using the formula:
0.1 M x 25 mL = M2 x 30 mL
M2 = (0.1 M x 25 mL) / 30 mL = 0.0833 M
Therefore, the concentration of the NaOH solution is 0.0833 M.
