Could you pls explain this question

This is my homework qns:

A solution was made by dissolving 11.926g of Fecl3 of purity 97.03%, in water and brought to volume in a 100(plus minus)0.8mL volumetric flask. The final mass of the solution was found to be 108.732g.

Calculate the composition of the solution expressed as:

a)molarity
b)w/v%
c)W/w%

Ok for this qns i dun understand which is the composition of the solution they are refering to.Do they mean I need to find all the composition(water, FeCl3  and final solution) or is it only one of them?

Good question. That is, your question about the bad question is a good one.

I would assume you are to calculate concentration of FeCl3, but if possible - ask for clarification.
