An object with a mass of 3.4 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?

Question

An object with a mass of 3.4 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

Archimedes principle

The volume of water displaced is equal to the volume of the object displacing the water.

Volume of water displaced = volume of the object = 30.1 ml - 25.1 ml = 5.0 mls

mass of the object = 3.4 g

Density = mass/volume

Density of object = 3.4 g/5.0 ml = 0.68 g/ml
