Question

An irregular piece of the metal is found to weigh 87.4g. It is then placed into a graduated cylinder that contains some liquid. The liquid in the cylinder has an initial volume of 18.46 ml. After the metal was added and the liquid's level rises to 24.14 mL afterward. What is the density of this piece of metal in g/mL units? Enter a number without units.

Answer 1

Initial volume = 18.46 mL

Final volume = 24.14 mL

Volume of metal = change in volume = V​​​​​​final - V​​​​initial

= 24.14 mL - 18.46 mL = 5.68 mL

Given mass of metal = 87.4 g

Now, density of metal = mass / volume

Density = 87.4 g / 5.68 mL = 15.387 g/mL
