Challenge Problems
Push your limits with advanced challenges
A chemist dissolves 15 g of NaCl in 200 g of water. Determine the molality of the solution and discuss its importance.
💡 Hint: Use the molar mass of NaCl (about 58.5 g/mol) to find moles.
A solution has a molality of 2.5 m when 100 grams of solute is added. Calculate the mass of the solvent in kg, and interpret why this value matters in boiling point elevation.
💡 Hint: Think about the colligative properties that change with more solute.
