You measure the volume of water in a graduated cylinder marked down to the tenth of a mL. It starts with a water level indicating 28 mL. You then drop an unknown object into the cylinder for a new level indication of 34.4 mL. You remove and dry the unknown object, measuring its mass to be 22.352 +/- 0.003g.
a) Calculate the density of the unknown object in kg/m3 . (Density = mass/volume). Unit conversion factors are known exact quantities
b) Find the absolute error in your answer for a.
c) Can this object be made of diamond? (Density of diamond is 3520 kg/m3 .) Recall that 1m3 = 106 cm3 = 106mL.

A graduated cylinder filled with water rests upside down in a container of water at 0 C. The water is 7.00 cm deep. Attached to the base of the cylinder is a small ring (but since the cylinder is upside down, the ring is at the highest elevation, available for grabbing). The base of the cylinder has mass 10.0 grams with ring included. The cylinder itself has radius 3.00 cm, height 40.0 cm, and mass 100.0 grams (including the base...
