200.0 mL OF A 5.10 M solution are diluted to 500.0 mL. What is the concentration of the resulting solution? *

erastova [34]

Answer:

Concentration of the resulting solution = 2.04 M

Explanation:

M1 = 5.10 M

V1 = 200.0 mL

V2 = 500.0 mL

M2 = ?

By modifying the volume of solution, keeping the amount of solute constant, the concentration changes. To perform the calculations, the equation will be:

$M1*V1=M2*V2$

Where M1 is the initial concentration of the solution, M2 the final concentration and V is the value of the volumes of the initial and final solution.

Clearing the value of M2 from the equation and replacing the values we have:

$M2=\frac{M1*V1}{V2} =\frac{5.10M*200mL}{500mL} =2.04M$
