![density = (mass)/(volume) \\](https://img.qammunity.org/2021/formulas/chemistry/college/2qztd1zu9lpwav17leag2cjjn695yipoje.png)
From the question
mass of magnesium = 11.81 g
volume = 6.80 mL
The density of the metal is
![density = (11.81)/(6.80) \\ = 1.73676470...](https://img.qammunity.org/2021/formulas/chemistry/high-school/awnmpk95x5zbz5ydf7pbunnhuxrhhp1ond.png)
We have the final answer as
1.74 g/mL
Hope this helps you
