Asaturated solution prepared at 70∘c contains 32.0 g cuso4 per 100.0 g solution. a 350 −g sample of this solution is then cooled to 0∘c and cuso4⋅5h2o crystallizes out. if the concentration of a saturated solution at 0∘c is 12.5 gcuso4/100 g soln, what mass of cuso4⋅5h2o would be obtained? [hint: note that the solution composition is stated in terms of cuso4 and that the solid that crystallizes is the hydrate cuso4⋅5h2o.] express your answer using two significant figures.
