35.18*g of potassium nitrate is dissolved in enough water to make 23.41*mL solution. What is [KNO_3]?

You could have asked this question more clearly.....

Explanation:

Generally, we want solubility in terms of mol*L^-1....i.e.

"Moles of solute"/"Volume of solution"

And here we got (I think)....

((35.18*g)/(101.10*g*mol^-1))/(23.41*mLxx10^-3*L*mL^-1)=14.9*mol*L^-1

Potassium nitrate is exceptionally soluble in water, and here I don't think you even have a saturated solution. What does "saturated" mean in this context?
