You have a 100.0-mL graduated cylinder containing 50.0 mL of water. You carefully place a 180-g piece of brass (density = 8.56 g/mL) into the water. What is the final volume reading in the graduated cylinder?

Therefore the final volume reading in the graduated cylinder is 71.028 mL.

Explanation:

Density: Density is determined by dividing the mass of the material with the volume of the material.

The S.I unit of mass is Kg

The C.G.S unit of mass is gram

The S.I unit of volume is m³

The C.G.S unit of volume is cm³

Therefore S.I unit of density is = Kg/m³

and C.G.S unit is g/cm³.

given that the mass of brass = 180 g

And the density of brass = 8.56g/mL

We know that,

The graduated cylinder is containing 50.0 mL of water.

After the placing the brass into the Cylinder, then the volume become

=(volume of water+ volume of brass)

=(50.0+21.028)mL

=71.028 mL

Therefore the final volume reading in the graduated cylinder is 71.028 mL.

elements make up everything, and they combine to make compounds.

the answer is c
