dlinn [17]

Answer:

The answer is

<h2>1.74 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of magnesium = 11.81 g

volume = 6.80 mL

The density of the metal is

density =  \frac{11.81}{6.80}  \\  = 1.73676470...

We have the final answer as

<h3>1.74 g/mL</h3>

Hope this helps you
