A certain chemical dissolves in water at a rate proportional to the product of the amount undissoved and the difference between the concentration in a saturated solution and the concentration in the actual solution. In 100 grams of a saturated solution, it is known that 50 g of the substance are dissolved. If when 30 g of the chemical are agitated with 100 g of water, 10 g are dissolved in 2 hrs, how much will be dissolved in 5 hrs?

Total mass of saturated solution = 100 gm Mass of solute that can be dissolved in solution = 50 gm

Answered: A certain chemical dissolves in water…
