If 2 moles of NaCl are dissolved in 1 kg of water, what will be the boiling point elevation? Use \(K_b = 0.52° C/m\). Assume NaCl dissociates completely to 2 particles.
💡 Hint: Remember to factor in the dissociation of NaCl.
A solution is prepared by dissolving 1 mol of glucose (C6H12O6) in 1 kg of water. Calculate the freezing point depression if \(K_f = 1.86° C/m\).
💡 Hint: Consider that glucose simply adds to molality.
