B.between 250 g of sugar and 350 g of sugar in 100 g of water. C.between 350 g of sugar and 400 g of sugar in 100 g of water. D.more than 400 g of sugar in 100 g of water.

9 th Grade Science #4. In order to produce rock candy at 20 degrees Celsius from a solution of 300 g of sugar not completely dissolved in 100 g of water, the solution must be: F.first heated above 60 degrees Celsius, then slowly cooled to 20 degrees Celsius. G.slowly stirred at 20 degrees Celsius. H.slowly cooled to 0 degrees Celsius. J. slowly cooled below 0 degrees Celsius, then heated to 20 degrees Celsius and stirred.
