Is needed to prepare 250 mL of a 0.30 M aqueous solution?

Quizplus · Accepted Answer

To find the volume of concentrated acetic acid needed to make a 0.30 M solution, we need to use the formula:
M1V1 = M2V2
where M1 is the concentration of the concentrated acetic acid solution, V1 is the volume of concentrated solution needed, M2 is the desired concentration of the diluted solution, and V2 is the final volume of the diluted solution (250 mL).
Rearranging the formula, we get:
V1 = (M2 x V2)/M1
Substituting the given values, we get:
V1 = (0.30 M x 250 mL)/11.7 M
V1 = 6.38 mL
Therefore, the volume of concentrated acetic acid needed is 6.38 mL, which is closest to option B (4.3 mL).
