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.
Volume of solute = 25 mL
Volume of solvent = 150 mL
% = ( volume of solute / volume of solvent ) x 100
% = ( 25 / 150 ) x 100
% = 0,166 x 100
= 16.6 % v/v
hope this helps!

take the Fahrenheit temperature deduct 32, multiply by 5, and the last divide by 9.
Like this
86 - 32= 54
54 X 5= 270
270/9=30
