You have a beaker filled with 1420 μL of water and decide to mass the water on an balance and find the mass is 1.421 g. After this measurement, you spill acetone into the water. You notice the beaker now has 1820 μL of liquid and a mass of 1.738 g. Remembering that substances less dense than water will float and those more dense than water sink, is the acetone floating at the top of the beaker, or did it sink to the bottom of the beaker?
Floating. Density of water = 1.00 g/mL and density of Acetone = 0.793 g/mL
