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 con
1 answer:
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
=0.756 M
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.

The structure of the alkyl bromides used in a malonic ester synthesis of ethyl 2-methyl-4-pentenoate are as drawn in the attached image.
<h3>Ethyl 2-methyl-4-pentenoate by Malonic ester synthesis.</h3>The malonic ester synthesis is a chemical reaction characterized by the alkylation of diethyl malonate or a similar ester of malonic acid at the carbon alpha (directly adjacent) to both carbonyl groups, and subsequently converted to a substituted acetic acid.
Hence, it follows from the structure of Ethyl 2-methyl-4-pentenoate that the alkyl bromides used are Ethyl bromide and methyl bromide.
