Answer:

The answer is 0.6923 mL

Explanation:

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

[tex]Density = \frac{mass}{volume} [/tex]

Making volume the subject we have

[tex]volume = \frac{mass}{Density} [/tex]

From the question

Density = 728 g/mL

mass of nickel = 5.040 g

Substitute the values into the above formula and solve for the volume

That's

[tex]volume = \frac{5.040}{728} \\ = 0.692307[/tex]

We have the final answer as

Volume of nickel = 0.6923 mL

Hope this helps you
