Problem- The solubility of Ba(OH)2 * 8H2O in water at 15 degrees c is 5.6g per 100 g of water. (A) what is the molality of a saturated solution at 15 degrees c? What is the molality of the hydroxide ions?
Solve the above problem and provide steps with explanation
Carbon monoxide (CO) has a much smaller dipole moment than expected. This observation has puzzled chemists and led to much argument about the nature of the bonding in the molecule.
