The given formula contains two carbon along with six hydrogen and an oxygen.
The possible isomers from are ethanol and dimethyl ether.
Ehtanol is an alcohol containing a hydroxyl group whereas dimethyl ether is an ether containing an oxygen between two methyl
The structure of two isomers are:
Answer:
9.28
Explanation:
pOH refers to a measure of hydroxide ions concentration. pOH tells about the alkalinity of a solution. If pOH is less than 7 then aqueous solutions are alkaline, acidic if pOH is greater than 7 and neutral if pOH is equal to 7.
Concentration of the hydroxide ions = 1.9 x 10-5 M
pH =
pOH = 14 - pH
=14 - 4.72 = 9.28
Density is intensive because it is the ratio of two extensive properties that is mass to volume.
<h3>What is Density ?</h3>Density is defined as mass per unit volume. S.I unit if density is kg/m³.
It is expressed as
Density = or
Intensive property is the property which does not depend on the size of the system. Intensive property can be easily identified. Intensive property is the independent property. The size does not change in this.
Example of intensive property are Density, Freezing point, melting point, colour, Lustre, etc.
<h3>What is Extensive property ?</h3>Extensive property is the property which depend on the substance. Extensive property cannot be easily identified.
Example of extensive property length, weight, volume, mass etc.
Thus from the above conclusion we can say that Density is intensive because it is the ratio of two extensive properties that is mass to volume.

Question: The density (d) of a substance is an intensive property that is defined as the ratio of its mass (m) to its volume (v)
density = or
Considering that mass and volume are both extensive properties, explain why their ratio, density is intensive.
