Homework Help: chemistry

Posted by James on Friday, October 29, 2010 at 1:32pm.

The solubility of barium nitrate at 100C is 34 g/100 g of H2O and at 0C is 5.0 g/100g of H2O. If you start with 100 g of Ba(NO3)2 and make a saturated solution in water at 100C, how much water is required? If the saturated solution is cooled to 0C, how much Ba(NO3)2 is precipitated out of solution? The precipitated crystals carry along with them on their surface 4 g of H2O per 100 g of crystals.
