Moles of electrons:
The moles of electrons that are transferred are 12F
A balanced equation:
2 moles of Aluminium metal react with excess copper(II) nitrate.
![2Al + 3Cu{(NO_3)}_2 \rightarrow 2Al{(NO_3)}_3 +3 Cu](https://tex.z-dn.net/?f=2Al%20%2B%203Cu%7B%28NO_3%29%7D_2%20%20%5Crightarrow%202Al%7B%28NO_3%29%7D_3%20%2B3%20Cu)
Given:
Moles of Aluminium = 2
As Aluminium goes from 0 to +3 oxidation state
![Al \rightarrow Al^{3+} + 3e^-](https://tex.z-dn.net/?f=Al%20%5Crightarrow%20Al%5E%7B3%2B%7D%20%2B%203e%5E-)
And copper goes from +2 to 0
![Cu^{2+} + 2e^-\rightarrow Cu](https://tex.z-dn.net/?f=Cu%5E%7B2%2B%7D%20%2B%202e%5E-%5Crightarrow%20Cu)
On balancing the number of electrons we get:
For 1 mole of Al
is required.
Therefore for 2 moles of Al,
Total
F mole of electrons
Where F= Faraday's constant= 96500 C
So, 12F moles of electrons are transferred.

This question requires the knowledge of density.
The density of ethyl alcohol = 789 kg m⁻³
The density of water = 1000 kg m⁻³
Density = Mass / Volume
By applying ethyl alcohol,
789 kg m⁻³ = Mass / 0.9 m³
Mass = 710.1 kg
hence the mass of 0.9 m³ ethyl alcohol is 710.1 kg.
Then by applying water,
1000 kg m⁻³ = 710.1 kg / Volume
Volume = 0.7101 m³
= 0.7 m³
hence the equal water volume is 0.7 m³
