Question

3. A student was given an unknown metal. The student determined that the mass of the metal was 30.2 g. The student placed the

Answer 1

Answer:

15.1 g/mL

Explanation:

The density of a substance is defined as the ratio of the mass of the substance and the volume of the substance. Mathematically, it is expressed as:

Density = mass in grams/volume in mL

In this case, the mass of the metal = 30.2 g

Volume of the metal = volume of water displaced by the metal.

The volume of water displaced by the metal can be calculated as the final volume of water after placing the metal - initial volume of water before placing the metal.

Hence, volume of metal = 22.0 - 20.0 mL = 2.0 mL

Density of metal = 30.2/2.0 = 15.1 g/mL

The density of the metal is 15.1 g/mL

The identity of the metal is not in the table.
