Question

An object with a mass of 7.7 g raises the level of water in a graduated cylinder from 25.1 mL to 29.8 mL. What is the density of the object?
g/mL

Answer 1

Answer:

The answer is

1.64 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 = 7.7 g

volume = final volume of water - initial volume of water

volume = 29.8 - 25.1 = 4.7 mL

The density of the object is

$density = \frac{7.7}{4.7} \\ = 1.638297872...$

We have the final answer as

1.64 g/mL
