Problem
Two immiscible fluids, X and Y, are analyzed separately in a laboratory. For fluid X, a straight-line graph of mass versus volume passes through the origin and the point (20 mL, 15.6 g). For fluid Y, the corresponding straight line passes through the origin and the point (20 mL, 22.8 g). Assume perfect linearity for each fluid over the range of interest.
(a) Determine the density of each fluid in g/mL.
(b) A beaker initially contains 100 mL of fluid Y. The experimenter then gently adds 150 mL of fluid X on top. Calculate the combined mass of the liquids now in the beaker.
(c) Based on your densities from part (a), state which fluid will form the upper layer in the beaker and explain your reasoning.
