Question

The mass of a piece of metal is 30.4571 grams. When the piece of metal was dropped into a graduated cylinder that had an initial water volume of 6.45 cm³, the total volume increased to 9.90 cm³. What is the density of the piece of metal in g/cm³?

Answer 1

Answer: 8.824 g/cm³

Explanation: To find the density of the piece of metal, we must divide the mass by the volume of the metal. To find the metal's volume, we subtract the initial volume from the total volume.

Volume of metal = Final Volume - Initial Volume

Volume of metal = 9.90 - 6.45

Volume of metal = 3.45 cm³

Now, we can implement the metal's volume into the division process to find the density:

Density = 30.4571 ÷ 3.45

Density = 8.824 g/cm³

Hence, the density of the piece of metal is 8.824 g/cm³.
