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

The answer is

2.0 g/mL

Step-by-step explanation:

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

`density = (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 = (10)/(5) \\`

We have the final answer as

2.0 g/mL

Hope this helps you
