What is molarity?</h3>
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
Given data:
Molar mass of = 0.762 mol
Volume of solution = 405,576.398 mL = 405,576.398 mL/1000 = 405.576398 L
Solution:
Step 1: Calculating moles of
• Molarity =
• Putting the value in the given formula
• Moles of solute C8H18 = 
• Moles of solute C8H18 = 
Now,
Molarity =
Molarity =
Molarity =
Hence, is the of is in 405,576.398 mL.

Answer:
1. the bottom layer
2. aqueous HCI
3. the top layer
4.aqueous NaOH
5. mostly in the diethyl ether layer
Explanation:
Pure dimethylformamide is considerably more polar than hexane hence thee two solutions will form two phases with the pure dimethylformamide as the bottom layer.
If we want to extract aniline from chloroform, HCl must be added in order to give a salt that can be extracted into the aqueous layer.
For a mixture of methylene chloride and diethyl ether, the diethyl ether layer will be found as the top layer since it is considerably less polar than methylene chloride.
Benzyl alcohol can be extracted from a solution of chloroform by adding NaOH and extracting it into an aqueous layer.
A large partition coefficient for the extraction of naphthalene into diethyl ether from water means that naphthalene will be found mostly in the diethyl ether layer.
