Answer:

0.325M

Step-by-step explanation:

The following data were obtained from the question:

C1 =?

V1 = 28mL

C2 = 0.182M

V2 = 50mL

The molarity of the stock solution can be achieved by using the following equation:

C1V1 = C2V2

C1 x 28 = 0.182 x 50

Divide both side by 28

C1 = (0.182 x 50) /28

C1 = 0.325M

Therefore, the molarity of the stock solution is 0.325M
