If you think of it endothermic is when there is energy needed for the reaction to occur and exothermic is when the reaction releases energy
To start, 1 cubic centimeter = 1 milliliter, so now you have 1.11g/mL.
Now multiply 1.11 by 387 to get the mass of antifreeze in grams, since the mL is canceled out.
387 mL x 1.11g/mL = 429.57 g

Explanation:
90% of energy is lost. only 10% is left.
therefore the answer is B. 90%
