6. You are asked to calculate the density of an unknown metal block. The mass of the block was measured to be 83.0 g. When the block was placed in a graduated cylinder containing water, the volume of the block was measured as 17.2 mL. Calculate the density of this unknown metal.​

Answer :

Density of the unknown metal is 4.82 g/mL

  • A substance's density is defined as its mass per unit of volume. Density is most frequently represented by the symbol ρ.
  • The volume and mass of the substance must be known in order to compute density.

Given,

mass of block is 83 g

When the block was placed in a graduated cylinder containing water, the volume of the block was 17.2 mL.

we have to find density with the help of these two terms,

As we know,

Density = Mass/volume

therefore,

Density = 83 / 17.2

= 4.82 g/mL

thus, density of unknown metal block is 4.82g/mL
