    Solution Preview

    The solution is ethylene glycol and water.
    The mass percentage of this solution is 40% and this means 40% of the mass is ethylene glycol and 60% of the mass is water.

    Here I like to work with a total mass of the solution equal to 100 grams. The total mass is arbitrary, but 40% of 100 grams is 100 x (40/100) =40 grams.
    So we have 40 grams of ...
