Answer:
The answer is
<h2>55.56 cm³</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass of aluminum = 150 g
density = 2.7 g/cm³
The volume is

We have the final answer as
<h3>55.56 cm³</h3>
Hope this helps you
I believe Cl (chlorine) would have a -1 charge since H tends to have a +1 charge.
Hope this helps!!! :)
