Expert Solution
Step 1

“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.”.

 

Given,

Mass of cyclohexane=21.213 g=0.021213 kg

Freezing point of cyclohexane=6.29 oC

Mass of naphthalene =0.151 g

Freezing point of solution (cyclohexane+ naphthalene)=20.51 oC

m is molality
