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
Hope this helps you
