Question 1 of 7
The solubility of KNO3\mathrm{KNO_3} is 110 g110\ \mathrm{g} at 60 ∘C60\ ^\circ\mathrm{C} and 31.6 g31.6\ \mathrm{g} at 20 ∘C20\ ^\circ\mathrm{C}. When 105 g105\ \mathrm{g} of saturated KNO3\mathrm{KNO_3} solution at 60 ∘C60\ ^\circ\mathrm{C} is cooled to 20 ∘C20\ ^\circ\mathrm{C} (no water evaporates), what mass of KNO3\mathrm{KNO_3} crystals forms? ( ).
