Solve the following problem by the Hydrated Bases method and the formula.

A crystallizer-evaporator is fed with 80,000 lb/h of an aqueous solution containing 25% by weight of MgSO4 at 200F. The solution is cooled to 130F and evaporates 30,000 lb/h of water. Calculate:

1. The % of MgSO4 recovered.

2. Crystal production
