Answer:
9.0 g/cm³
Step-by-step explanation:
Density can be computed with the formula:
![D=(M)/(V)](https://img.qammunity.org/2020/formulas/chemistry/middle-school/6vje53719041vqy0q3842pvxwbq9tzcobu.png)
Where:
D = Density
M = Mass
V = Volume
In your problem we are given:
84 cm³ = volume
760 g = mass
So we just plug in our given into the formula:
![D=(M)/(V)](https://img.qammunity.org/2020/formulas/chemistry/middle-school/6vje53719041vqy0q3842pvxwbq9tzcobu.png)
![D=(760g)/(84cm^(3))](https://img.qammunity.org/2020/formulas/chemistry/middle-school/7xvjfx4edo044niv2vgmcuz2pkrup8wv93.png)
![D=9.05g/cm^(3)](https://img.qammunity.org/2020/formulas/chemistry/middle-school/imrmvkm6i6vrzjhaecp92w3hgs9qu3qy1r.png)
The answer would then be:
9.0 g/cm³
