    • no salt grains are visible after stirring
    • the liquid looks the same throughout

  3. Which method could separate oil and water?

    • sort the pieces by hand
    • filter the water through paper
    • pour or skim off the oil layer
    • use a magnet to remove the iron

  4. The graph shows mass before and after making salt water. What does it support?

    • a solution has no mass
    • the matter disappears after mixing
    • all mixtures become pure water
    • the total mass stays the same when no material is lost
