In each pair, identify the solution that will have a lower freezing point. Explain. 1.1.0 mole of glycerol (nonelectrolyte) and 2.0 moles of ethylene glycol (nonelectrolyte) each in 1.0 kg of water 2.0.50 mole of KCl (strong electrolyte) and 0.50 mole of MgCl₂ (strong electrolyte) each in 1.0 kg of water Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. three more one four 0.50 mole of KC1 KCI six 1.0 mole of glycerol 2.0 moles of ethylene glycol MgCl remains unchanged decomposes 0.50 mole of MgCl₂ dissociates less two Reset Help 1. 2.0 moles of ethylene glycol in 1.0 kg of water will have a lower freezing point because it has two particle in solution. 2. 0.50 mole of MgCl₂ in 1.0 kg of water has a lower freezing point because each MgCl₂ dissociates in water to give three particle(s), whereas each KCI dissociates to give only two particle(s). !

1. 2.0 moles of ethylene glycol in 1.0 kg of water will have a lower freezing
point because it has two particle in solution.
2. 0.50 mole of MgCl₂ in 1.0 kg of water has a lower freezing point because
each MgCl₂ dissociates in water to give three particle(s), whereas each
KCI dissociates to give only two particle(s).
