    Key Questions:

    1. What units are used for the measurement of concentration of a solution?
      • The standard measures of concentration of a solution are: grams per dm3 (g/dm3) or moles per dm3 (mol/dm3)
    2. What is the concentration of a solution that has 37g of solute dissolved in 100cm3? Give your answer in dm3.
      • The concentration would be 37g / 100cm3. To convert this to dm3 divide answer by 1000 = 0.0037g/dm3.
    3. (HT only) What is the equation that relates the mass of a solute, the volume of a solution and the concentration of the solution?
      • concentration of solution (g/dm3) = mass of a solute (g) / volume of solution (dm3)
    4. Why industrially is high atom economy important?
      • It is important for sustainable development and for economic reasons to use reactions with high atom economy.
