A 28.00 mL sample of calcium
chloride stock solution
produces a 0.182 M solution
when diluted with 50.00 mL of
water. What is the molarity of
the stock solution?
SOLUTIONS

0.325M

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

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
