Answer:
The volume of the solution must be increased to 71.429 millimeters by adding 66.359 millimeters of solute to reduce molarity from 6.82 M to 0.49 M.
Explanation:
The molarity is a unit used for solution that is equivalent to the amount of moles of solute per unit volume of solution. That is:
Where:
- Amount of moles of solute, measured in moles.
- Volume of the solution, measured in liters.
To reduce the molarity of the solution, more millimeters of solvent should be added. Firstly, the amount of moles of acetic acid inside the 6.82 M solution needs to be determined (
and 
):
Now, the resulting volume of solution after diluting the acetic acid solution is: (
and ):
(1 L = 1000 mL)
The amount of solvent needed to dilute the solution is:
(1 L = 1000 mL)
The volume of the solution must be increased to 71.429 millimeters by adding 66.359 millimeters of solute to reduce molarity from 6.82 M to 0.49 M.
Within each functional group, the boiling points of members of the group vary according to molecular weight. Therefore, one cannot deduce any functional group from boiling points.
Organic compounds are divided into families called homologous series. Each homologous series has a functional group common to all the members of the series. As a result of this, the chemical properties of all the members of the homologous series are similar.
However, the boiling points of the members of a homologous series vary according the their molecular weights. As such, boiling points can not be used as evidence to classify substances into any particular homologous series.
Summarily, one cannot deduce any functional group from physical properties.
