Answer:
Density = 0.8 kg/L
Step-by-step explanation:
The density of a substance can be found by using the formula
![Density = (mass)/(volume)](https://img.qammunity.org/2021/formulas/chemistry/high-school/el4r75hf1brsg5k4a45db8ptpkl6z9kys6.png)
From the question
mass = 7.2 kg
volume = 9.0 L
Substitute the values into the above formula and solve for the density
That's
![Density = (7.2)/(9)](https://img.qammunity.org/2021/formulas/chemistry/high-school/zrvzaltvert95cp4e5gdir2nh0eqgijj1e.png)
We have the final answer as
Density = 0.8 kg/L
Hope this helps you
