The molecular weight of acetanilide is 135.17 grams/mole. The solubility of acetanilide in water is 5.5 grams/100 mL at 100°C and 0.53 grams/100 mL at 0°C. You are given a 30.0 gram sample of acetanilide that has been contaminated with insoluble sawdust. For every 10.0 grams of sample, 1.5 grams of that sample is sawdust. Theoretically, if you use just enough water to dissolve the entire sample of acetanilide, how much acetanilide will crystallize upon cooling to 0°C? 25.5 grams 23.0 grams 105.2 grams 109.7 grams 2.5 grams
