  1. How would you prepare 60 mL of a 10% (w/v) NaOH solution?
    10% of 60 ml is 6. In this case, 6 grams of NaOH. Take 6 grams of NaOH and dilute to a volume of 60ml with water. It is important that you dilute the solid to 60 ml and not simply add it to 60 ml of water.
  2. What is mass fraction?
    is the ratio of one substance with mass to the mass of the total mixture (w/w)
  3. what is the mass concentration?
    is defined as the mass of a constituent  divided by the volume of the mixture
  4. what is the volume fraction?
    is defined as the volume of a constituent divided by the volume of all constituents of the mixture prior to mixing
