Question

A block with a mass of 10g is dropped into a graduated cylinder with 20 mL of water. The water rises to 25 mL. What is the density of the rock?

Answer 1

Answer:

The answer is

2.0 g/mL

Explanation:

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

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

From the question

mass of block = 10 g

volume = final volume of water - initial volume of water

volume = 25 - 20 = 5

volume = 5 mL

The density of the block is

$density = \frac{10}{5}$

We have the final answer as

2.0 g/mL

Hope this helps you
