A saturated solution is prepared at `70^(circ)C` containing `32.0g CusO_(4).5H_(2)O per 100 g` solution. A `335 g` sample of this solution is then cooled to `0^(circ)C` so that. `CuSO_(4).5H_(2)O` crystallises out. If the concentration of a saturated solution at `0^(circ)C` is `12.5g CuSO_(4).5H_(2)O per 100.0 g` solution, how much of `CuSO_(4).5H_(2)O` is crystallised?

Answer

`74.47 g`;
