At 20°C, the solubility of potassium carbonate, K2CO3, is 110.3 g/100. mL of water. In the laboratory, a
student mixes 215 g of K2CO3 with 175. g of H2O at a temperature of 20°C. (9.3)
a) How much of the K2CO3 will dissolve?
b) Is the solution saturated or unsaturated?
c) What is the mass, in grams, of any solid K2CO3 left undissolved on the bottom of the container?
