Question

The solubility of a compound (molar mass = 175 g/mol) in water is found to be 7.75 grams per 100.0 grams of water at 25oC.  Calculate the molality of the compound in a saturated aqueous solution at 25oC.  Your answer should have 3 significant figures.  Do not include the units with your answer, but the units should be molality.

Expert Solution
Step 1

Molality = Number of moles of solute/Mass of solvent in Kg

Number of moles = Mass/molar mass
