a chemist encounters an unknown metal. They drop the metal into a graduated cylinder containing water, and find the volume change is 3.2 mL. If the metal weighs 1.5g, what is the density in g/mL of the metal?

The density of metal will be "0.469 g/mL".

The given values in the question are:

Now,

The density of metal will be:

→

By substituting the given values, we get

→              

→              

Thus the above is the appropriate answer.

The density of the metal is 0.47 g/mL

The density of an object is defined as the mass of the object per unit volume of the object.

With the above formula, we can obtain the density of the metal. This is illustrated below:

Volume of metal = change in volume of water = 3.2 mL

Mass of metal = 1.5 g

Density = mass / volume

Density = 1.5 / 3.2

Therefore, the density of the metal is 0.47 g/mL
