Answer:
3.68 grams per cubic centimeter
Explanation:
Intensive properties are useful for identifying a substance simply because these properties do not depend on the amount of sample, nor do they change according to conditions.
The correct answer choice which is a physical property of matter is boiling point.
Polymers are long chains of <u>molecules</u>
The method which I would use to separate two liquids with different boiling points is <u>distillation</u>
The particles are located in the nucleus of an atom are protons and neutrons
The type of molecular model which is used to represent very large molecules like proteins is ribbon diagram
The methods which is used to separate a mixture according to the size of the particles are filtration and chromatography
<h3>What is a mixture?</h3>
A mixture is a substance which contains two or more constituents which can easily be separated by physical means
So therefore, the methods which is used to separate a mixture according to the size of the particles are filtration and chromatography

The answer to the question is a. Passage I contains a character study, but Passage 2 focuses more on concepts.
for all who were wondering
For the compound B the following statement is correct-
B. It is an ether because it is unable to form a hydrogen bond, so it is less soluble in water.
The solubility of alcohol in water depends upon the capability of formation of hydrogen bond in the solute. Now in alcohol the -OH group is polar in nature which enhance the possibility of hydrogen bond formation and it is more soluble in water.
On the other hand although there presence a -O- functional group in ether. It is less soluble in water due to non polarity of the functional group.
From the given data it is seen that compound A is more soluble in water than compound B. Thus it may be predicted that compound A is alcohol and B is ether.
Henceforth, for the compound B the following statement is correct-
B. It is an ether because it is unable to form a hydrogen bond, so it is less soluble in water.
The reason of incorrect options:
A. compound B cannot be an alcohol as it is less soluble in water.
C. In ether the functional group is -O-, thus electronegative atom (O) is present.
D. As both the compound (alcohol and ether) has equal molecular mass thus the organic chain will be same in alcohol and the hydrogen bond interaction will be more prominent than the dispersion force between the -OH group.
