You are given 100.0 ml of a 2.0 M solution of KOH. What would be the molarity of the solution if it is diluted to a volume of 1000 ml?
|
|
2 M
|
|
|
0.02 M
|
|
|
0.2 M
|
|
|
0.002 M
|
Explanation:
Detailed explanation-1: -Final volume = 700 + 100 = 800 ml. M2 = 0.25 M. Hence, the molarity of resultant solution will be 0. 25 M.
Detailed explanation-2: -Answer: The molarity of solution is 0.5 M.
Detailed explanation-3: -250mL of 0.2M NaOH and 100mL of 0.5M NaOH solutions were added.
Detailed explanation-4: -Molarity of the solution M=2.8×100056×100=2856=12=0.5 M. Q.
