Question

In the laboratory, a student dilutes 18.9 ml of a 10.0 m perchloric acid solution to a total volume of 250.0 ml. what is the concentration of the diluted solution?

Answer 1

The concentration of the diluted solution is 0.756 M

Given,

Volume of stock solution (V1) = 18.9 mL

Molarity of stock solution (M1) = 10 M

Volume of diluted solution (V2) = 250 mL

M1V1 = M2V2

10*18.9=M2*250

$M_{2}$=0.756 M

Solution

A homogeneous mixture of two or more substances in relative proportions is referred to as a solution in chemistry. The limit of solubility is the point at which this mixture ceases to be a solution. Although the word "solution" is frequently used to refer to the liquid state of matter, solutions of gases and solids are also possible. Any of these three substances can be a solution. A mixture of liquids, gases, and solids can also make up a solution. Some solutions, like seawater, include a wide variety of solutes, including salts, oxygen, and organic compounds.
