A pycnometer is a device used to measure density. It weighs 20.455 g empty and 31.486 g when filled with water (d=1.00 g/cm3). Pieces of an alloy are put into the empty, dry pycnometer. The mass of the alloy and pycnometer is 28.695 g. Water is added to the alloy to exactly fill the pycnometer. The mass of the pycnometer, water, and alloy is 38.689 g. What is the density of the alloy?
