A student wants to determine the density of a plastic piece. Preliminary experiments indicate that the density of the plastic is greater than 0.85 g/ml, but less dense than water. In order to determine the density of the plastic piece, the student will form an aqueous solution having the same density as the plastic piece. Which of the following liquids should be mixed with water to form a solution having the same density as the plastic piece?

A. Alcohol               B. Mineral Oil                          C. glycerol                        D. methylene chloride
