We wish to determine the density of a metallic alloy at 25oC. This is done as follows. A pycnometer weighs 20.455g empty and 31.486g when filled with water at 25oC. The density of water at 25oC is 0.99704 g/mL. Pieces of the alloy are put into the empty, dry pycnometer. The mass of the alloy and the pycnometer is 28.695g. Water is added to the pycnometer to exactly fill it. The mass of the entire system is now 38.689g. What is the density of the alloy
