Solution: By referring to the figure above, determine the minimal mass of each of the following salts required to form a saturated solution in 400 g of water at 30oC.Ce2(SO4)3

Problem

A graph has temperature in degrees C on the x-axis, ranging from 0 to 100 with intervals of 10. Solubility (grams of salt in 100 grams of water) is on the y-axis, ranging from 0 to 100 with intervals of 10. Nine ionic compounds are plotted. The solubility of most salts in water increases with temperature, but NaCl is relatively unaffected by temperature increases and Ce2(SO4)3 actually decreases initially with increasing temperature and then remains flat.

By referring to the figure above, determine the minimal mass of each of the following salts required to form a saturated solution in 400 g of water at 30oC.
