Molar solubility is measured as moles of dissolved solute per litre of:
AConcentrated acid
BSaturated solution
CPure solid solute
DDistilled cold water
Answer & Solution
Correct answer: B. Saturated solution
1. Molar solubility needs a stated volume basis.
2. Solubility calculations are most conveniently performed using molar solubility.
3. Molar solubility is measured as moles of dissolved solute per liter.
4. That litre is a litre of saturated solution.
