A saturated solution of barium chloride at 30 degrees celcius contains 150g of water. How much additional barium chloride can be dissolved by heating this solution by heating this solution to 60 degrees.

Solubility of Bacl @ 30 degrees=38.2g/100g water
solubility of Bacl @ 60 degrees =46.6g/100g water

1. How much BaCl2 do you have in the saturated solution. That is
38.2 x (150/100) = ? g BaCl2 @ 30 C.

How much CAN you have at 60 C (note the correct spelling of celsius)?
46.6 x (150/100) = ? g BaCl2 @ 60 C.
The difference is the amount BaCl2 that can be added.
