Answer:
6,613 M
Explanation:
Dilution is the process of reducing the concentration of a solute in solution, mixing initial solution with more solvent.
The concentration of Solution B is:
23,881 M × = 9,552 M
Because the initial eight parts are diluted to 12+8 parts.
Thus, concentration of solution C is:
9,552 M × = 6,613 M
