200.0 mL of a 0.845 M solution of KCl is diluted to 600.0 mL. What is the new concentration of the solution?

The new concentration of the KCL solution is 0.150M

HOW TO CALCULATE CONCENTRATION:

The concentration or molarity in mol/L or M of a solution can be calculated using the following formula:

C1V1 = C2V2

Where;

C1 = initial concentration of the solution

C2 = final concentration of the solution

V1 = initial volume of the solution

V2 = final volume of the solution

According to the information given in this question, we have the following:

V1 = 200mL

V2 = 800mL

C1 = 0.600 M

C2 = ?

C2 = C1V1 ÷ V2

C2 = (0.600 × 200) ÷ 800

C2 = 120 ÷ 800

C2 = 0.15M

Therefore, the new concentration of the KCL solution is 0.150M.
