What is the relationship between layering of fluids and density?
Olin [163]

stellarik [79]

Answer:

<h3>The answer is 3.44 g/cm³</h3>

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

From the question

mass = 17.2 g

volume = 5 cm³

We have

density =  \frac{17.2}{5}  \\

We have the final answer as

<h3>3.44 g/cm³</h3>

Hope this helps you
