Calculate the percent by mass of the solute methylene chloride in a solution produced by combining 0.891 kg of CH2Cl2 to 3.20 kg of the solvent (C2H5)2O.
A mixture is expected to contain 9.2 x 10-4 M SO42- and 1.6 x 10-3 M C2O42-. If the Ksp values for BaSO4 and BaC2O4 are 1.1 x 10-10 and 1.0 x 10-6, respectively, determine if Ba2+ can be added to precipitate 99% of the SO4 2- from the solution wit..
