If you can please explain step by step for each question.

Problem 1, Question 1.

Cyclohexae, C6H12, melts at 6.55 oC and has a freezing point depression constant of kfp = -20.0 oC/m (where m is molality). You want to determine the molar mass of an unknown pure compound using the colligative property of freezing point depression. You weigh out 83.561 g of cyclohexane, and confirm that its melting point is 6.55 oC. You then mix 2.566 g of your unknown compound with the cyclohexane and find that the solution melting point is now 3.23 oC.

What is the If you can please explain step by step for each quTfp (with units of oC)?

Problem 1. Question 2.

What is the solution molality (with units mol/kg-solvent)?

Problem 1. Question 3.

How many moles of the unknown compound are there (with units of mol)?

Problem 1, Question 4.

What is the molar mass of the unknown compound (with units of g/mol)?
