Question

the solubility of acetanilide in hot water is 5.5g/100mL at 100 and its solubility in cold water is 0.53g/100mL at 0. what is the minimum volume of hot water that will be needed to dissolve 6g of acetanilide

Answer 1

I assume the solubility of 5.5 g in 100 mL of water. You will need
100 mL H2O x (6.0/5.5) = ? mL H2O to dissolve 6.0 g acetanilide.
