Please help me answer part a and b please

Answer the following in regard to the solution of hot chocolate:

1. Find a solution within your home: Hot Chocolate
2. Identify the solute (just pick one if there are multiple ingredients), solvent, and phases of each: Hot water (liquid) is the solvent, and the chocolate powder (solid) is the solute. When I put the chocolate powder into the glass of hot water, the water dissolves the chocolate powder.

a) Explain how the solution is formed by discussing the changes in solute-solute interactions, solvent-solvent interactions, and solute-solvent interactions. Be sure to explain the relative strengths of each of the interactions.

b) Based on the solute you identified, what is the van't Hoff factor for your solution? Explain how you know. Identify a different solute that would have a different van't Hoff factor. How are colligative properties affected by the value of the van't Hoff factor?
