Use the correct sig digs and units through out.
1. A solid metal sphere with a mass of 18.45g is added to 21.7 mL of water in a graduated cylinder. The water
level rises to 26.8 mL. Calculate the density of the sphere.(3 pts)
2. An empty graduated cylinder has a mass of 32.4257 g. A 10.0 mL sample of an unknown liquid is added to
the cylinder. The mass is now 40.1825 g. Determine the density of the liquid. (3 pts)
3. What is the density of a metal cube that is 1.30 cm in length and has a mass of 8.402 g. (2 pts)
4. The handbook density of gold is 19.3 g/cm3 . In the lab a student observes it to 18.4 g/cm3. What is her per
cent error? (2 pts)
