If 5.6 grams of potassium hydroxide is added to enough water to make 950 ml of solution, what is the concentration of the potassium?

Well, to be a smart aleck, I would say it's 5.6g/950 mL since you didn' specify %, M, m, or what.
If you want molarity, M, then
mols KOH = grams/molar mass
and M = mols/L solution.
