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

c, liquids evaporate, creating a gas

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
