An irregularly shaped piece of metal with a mass of 105 g was placed in a graduated cylinder that contained 25.00 mL of water. This raised the water level to 45.35 mL. What is the density of the metal?
A) 0.238 g/mL
B) 2.3 g/mL
C) 4.2 g/mL
D) 5.16 g/mL
E) 20.35 g/mL

To find the density, we need to use the formula:

density = mass / volume

We already have the mass of the metal, which is 105 g. To find the volume of the metal, we need to subtract the initial volume of water (25.00 mL) from the final volume of water (45.35 mL).

volume of metal = final volume - initial volume
volume of metal = 45.35 mL - 25.00 mL
volume of metal = 20.35 mL

Now we can plug in the values we have:

density = mass / volume
density = 105 g / 20.35 mL
density = 5.16 g/mL

Therefore, the correct answer is D.
