Questions
  1. Statement is true
    Yes
    Statement
    Molarity is moles of solute per litre of solution.
  2. Statement is true
    Yes
    Statement
    Molality is moles of solute per kilogram of solvent.
  3. Statement is true
    No
    Statement
    Molarity is measured per kilogram of solvent.
  4. Statement is true
    Yes
    Statement
    Molality uses a mass, so temperature does not change it.
  5. Statement is true
    Yes
    Statement

Complete the statement
Colligative comes from Latin, where co means {0} and ligare means to {1}. A colligative property depends on the NUMBER of solute particles rather than what they {2}.
The word itself explains the idea. Source: syllabus Chemistry, Ch 1 Solutions.
