A student dissolves an entire impure same of CuSO4 in enough distilled water to make 100 mL of solution. The student finds the concentration of CuSO4 to be 0.15. Calculate the number of moles of CuSO4 that were in the impure sample of CuSO4.

to make a supersaturated solution, make a saturated solution of sugar by adding 360 grams of sugar to 100 ml of water at 80 degrees celsius. when the water cools back down to 25 degrees, that 360 grams of sugar will still be dissolved even though the water should only dissolve 210 grams of sugar.
