Answer:
The answer is
7.31 mL
Step-by-step explanation:
The volume of a substance when given the density and mass can be found by using the formula
![volume = (mass)/(density)](https://img.qammunity.org/2021/formulas/chemistry/high-school/2meaxway3s2yhgqhirhno7x2n2gdm8n6sg.png)
From the question
mass of substance = 28.6 g
density = 3.91 g/cm³
The volume is
![volume = (28.6)/(3.91) \\ = 7.31457800](https://img.qammunity.org/2021/formulas/chemistry/high-school/d79m4gmu0hfej4067dfptf80j7jctryo8r.png)
We have the final answer as
7.31 mL
Hope this helps you
