Question

A piece of aluminum has a mass of 12.0 g. When it is placed into a graduated

cylinder with 14.0 mL of water, the water level rises to 18.5 mL. What is the density
of aluminum?
0 2.66667g/ml
O 2.67 g/mL
O 2.667g/mL
O 2.7 g/mL

Answer 1

The answer is 2.7 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 = 12 g

volume = final volume of water - initial volume of water

volume = 18.5 - 14 = 4.5 mL

So we have

`density = (12)/(4.5) \\ = 2.66666666...`

We have the final answer as

2.70 g/mL

Hope this helps you
