Question

If 50.0 mL of the solution in the above question is diluted in a volumetric flask to make 250.0 mL of solution, what is the concentration of the new diluted solution?

a) 0.12 M
b) 0.024 M
c) 0.44 M
d) 0.22 M

Answer 1

The concentration of a diluted solution can be calculated using the equation M1V1 = M2V2, but the initial concentration (M1) is needed in order to provide a specific answer. Since M1 is not provided in the question, we cannot determine the exact final concentration (M2) of the new diluted solution.

Step-by-step explanation:

The question concerns the dilution of a solution, which is a common concept in chemistry.

When a solution is diluted, the number of moles of solute present in the solution remains the same; only the volume of the solvent changes. Therefore, to find the concentration of the new diluted solution, you can use the equation:

M1V1 = M2V2

where M1 and V1 are the molarity and volume of the initial solution, and M2 and V2 are the molarity and volume of the final diluted solution.

However, the initial concentration (M1) is not provided in the question.

Generally, to solve a problem like this, you would rearrange the equation to solve for M2:

M2 = (M1V1) / V2

For example, if you were given that the initial concentration (M1) is 0.120 M, and you wanted to dilute 50.0 mL of this solution to a final volume (V2) of 250.0 mL, you would calculate:

M2 = (0.120 M × 50.0 mL) / 250.0 mL

M2 = 0.024 M

However, since the initial molarity is not provided, the specific answer cannot be determined from the information given in the question.
