59. A pycnometer is a device used to determine density.
It weighs 20.455 g empty and 31.486 g when filled with
water (d = 1.000 g/cm'). Pieces of an alloy are put into
the empty, dry pycnometer. The mass of the alloy and
Pycnlometer is 28.695 g. Water is added to the alloy to
exactly fill the pycnometer. The mass of the pycnometer.
