Answer:

2.58 mL

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

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

From the question we have

mass = 31 g

density = 12 g/mL

[tex]volume = \frac{31}{12} \\ = 2.58333[/tex]

We have the final answer as

2.58 mL

Hope this helps you
