Challenge Problems
Push your limits with challenges.
Question 1
A chemist prepares a 1.5 L solution of NaCl with a molarity of 3 M. How many grams of NaCl did they dissolve? (Molar mass of NaCl = 58.5 g/mol)
💡 Hint: Remember to use the formula that relates moles, molarity, and volume.
Question 2
If a compound has a van’t Hoff factor of 2 and it’s responsible for a freezing point depression of 2°C in a 0.5 m solution, calculate its normal freezing point value.
💡 Hint: You will need to revert to the original freezing point of the solvent.
