Answer: The molarity of the solution is 0.125 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L
moles of =
Now put all the given values in the formula of molality, we get
Therefore, the molarity of the solution is 0.125 M
Answer:
The student did not lose any organic product in the aqueous layer
Explanation:
From the question;
After addition of hydrochloric acid, a student removes the lower aqueous layer and extracts the aqueous phase with diethyl ether (0.5 mL).
The only possible way the student could have lose the product was if there are some basic group e.g in the compound which have a tendency of forming
salt.
Also these compound could be regenerated from aqueous layer by neutralizing the aqueous layer with basic solution , for example; by using sodium hydroxide (NaOH) in which the extraction is then followed by the usage of Diethyl ether.
