A student determines that the mass of a metal rod
is 12.0 g. He places 10.0 mL of water in a 25 ml
graduated cylinder. When the metal rod is placed
in the water, the graduated cylinder then reads
15,0 mL. What is the density of the metal rod?

Answer:

Explanation:

There's a great many assumptions in this question. We have to assume  that the rod was completely immersed. We also have to note that we can read the volumes to 3 places accurately. School graduated cylinders are not that accurate.

Leaving those objections aside,  here is how the question should be done.

Final volume = 15.0 mL

Initial volume = 10.0 mL

Water displaced = 5.0 mL

The amount of water displaced is the same as the volume of the metal rod.

Finally the mass of the rod is 12.0 grams.

Density = mass / volume

Density = 12.0 grams / 5.0 mL

density= 2.4 grams / mL   a mL and a cc^3 are the same thing.

density = 2.4 grams / cc^3
