Question

When an irregularly shaped chunk of an unknown metal with a mass of 25.32 g was placed in a graduated cylinder containing 25.00 mL of water, the water level in the cylinder rose to 28.22 mL. What is the density of this unknown metal?

Answer 1

Answer: The density of the unknown metal is 7.86 g/ml.

Explanation:

Density is defined as the mass contained per unit volume.

`Density=(mass)/(Volume)`

Given : Mass of metal = 25.32 g

Volume of metal = volume of water displaced = (28.22 - 25.00) ml = 3.22 ml

Putting in the values we get:

`density=(25.32g)/(3.22ml)`

`Density=7.86g/ml`

Thus the density of the unknown metal is 7.86 g/ml
