Answer:
The answer is
<h2>2.64 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 611 g
volume = final volume of water - initial volume of water
volume = 256.7 - 25.1 = 231.6 mL
The density of the metal is

We have the final answer as
<h3>2.64 g/mL</h3>
Hope this helps you
<u>Answer:</u> The correct answer is Option E.
<u>Explanation:</u>
Every balanced chemical equation follows law of conservation of mass.
This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical equation for the reaction of aluminium and water follows:

The coefficient of Aluminium is 2.
Hence, the correct answer is Option E.
