The chart is attached below and the options are as follow,
A Benzene
B Methanol
C Hexane
D Octane
Answer:
Option-B (Methanol) is the correct answer.
Explanation:
As we know that the substance given to student is soluble in water. Therefore, those substances which are soluble in water are polar in nature because water is polar in nature and Like Dissolves Like.
Hence, in chart it can easily be seen that Methanol is also polar in nature due to presence of -O-H (polar) bond. So, the substance will dissolve in it.

Answer:
Pyrite.
Explanation:
In this case, for the given samples, we compute the densities considering that the volume of each sample is computed by the difference between the volume of the water + sample and the volume of water:
Therefore, since the density of the samples are closer to the density of pyrite (5.01 g/cm³) we conclude that the samples are more like to be pyrite.
