Example: 1) If 40 kg of solute is dumped into a tank that contains 120 kg of solvent and at the end of 12 minutes, the concentration is observed to be one part in 30 parts, find the amount of solute in the solution at any time t. The saturation concentration is 1 part in 3 parts of the solvent. 2) A saturated solution known to contain 50 g of solute per 100 grams of solvent. If 30 g of the solute is agitated with 100 grams of water, 10 grams are dissolved in 2 hours. How much solute will dissolve in 6 hours? Solve the amount of solute at any time, t.
