Question

A chemist attempts to prepare some very pure crystals of borax by dissolving
100g of Na2B4O7 in 200 grams of boiling water. He then cools the solution slowly
until some borax crystallizes out. Calculate the grams of borax recovered in
the crystals per 100 grams of initial solution (Na2B4O7 plus water), if the residual
solution at 550C after the crystals are removed contains 12.4% Na2B4O7.What is
the percent yield or percent recovery of Na2B4O7.
