The identity of a sample of a metal that has a mass of 23.4 g and a volume of 3.0 mL is iron with a density of 7.8g/mL.
How to calculate density?
The density of a substance can be calculated by dividing the mass of the substance by its volume. That is;
Density = mass (g) ÷ volume (mL)
According to this question, a sample of a metal has a mass of 23.4 g and a volume of 3.0 mL. The density of the metal is as follows:
Density = 23.4g ÷ 3mL
Density = 7.8g/mL
Therefore, the identity of a sample of a metal that has a mass of 23.4 g and a volume of 3.0 mL is iron with a density of 7.8g/mL.
