Expert Solution

Step 1: Given data

Note: Since you have posted a question with multiple sub-parts, we will solve the first three subparts for you. To get the remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.

Mass of cyclohexane = 21.213 g

mass of naphthalene = 0.151 g

Freezing point of cyclohexane = 6.29⁰C

Freezing point of solution (cyclohexane + naphthalene) = 20.51⁰C.

Freezing point depression constant for cyclohexane, K_f= 20⁰C/mol/kg.
