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.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

the answer is na (sodium)
