An object with a mass of 6.9 g raises the level of water in a graduated cylinder from 25.1 mL to 30.4 mL. What is the density of the object?

The answer is

Explanation:

The density of a substance can be found by using the formula

From the question

mass of object = 6.9 g

volume = final volume of water - initial volume of water

volume = 30.4 - 25.1 = 5.3 mL

It's density is

We have the final answer as
