Question

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?

Answer 1

Answer:

The answer is

1.30 g/mL

Explanation:

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

$density = \frac{mass}{volume}$

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

$density = \frac{6.9}{5.3} \\ = 1.30188679...$

We have the final answer as

1.30 g/mL
