Question

An object with a mass of 7.5 g raises the level of water in a graduated cylinder from 25.1 ml to 30.1 ml. what is the density of the object?

Answer 1

1.5 g/mL is the density of the object.

Step-by-step explanation:

Mass of an object = 7.5 g

Initial level of the water in graduated cylinder = 25.1 mL

Final level of the water in graduated cylinder = 30.1 mL

Change in volume of water level = 30.1 mL - 25.1 mL = 5.0 mL

Change in volume of water level = Volume occupied by an object

Volume of an object = 5.0 mL

`Density=(Mass)/(Volume)`

`\Density=(7.5 g)/(5.0 mL)=1.5 g/mL`

1.5 g/mL is the density of the object.
