<h3>Answer:</h3>
1.5 × 10⁸ Kg of CO₂ / Year
<h3>Solution:</h3>
According to statement,
1 kwh generation produces = 0.73 Kg of CO₂
So,
700 kwh generation will produce = X Kg of CO₂
Solving for X,
X = (700 kwh × 0.73 Kg) ÷ 1 kwh
X = 511 Kg of CO₂ / Year
Also, as calculated,
1 household produces = 511 Kg of CO₂ / Year
Then,
300,000 households will produce = X Kg of CO₂ per Year
Solving for X,
X = (300000 households × 511 Kg) ÷ 1 household
X = 153300000 Kg of CO₂ / Year
Or,
X = 1.5 × 10⁸ Kg of CO₂ / Year
Answer is: boiling point will be changed by 4°C.
Chemical dissociation of aluminium nitrate in water: Al(NO₃)₃ → Al³⁺(aq) + 3NO⁻(aq).
Change in boiling point: ΔT =i · Kb · b.
Kb - molal boiling point elevation constant of water is 0.512°C/m, this the same for both solution.
b - molality, moles of solute per kilogram of solvent., this is also same for both solution, because ther is same amount of substance.
i - Van't Hoff factor.
Van't Hoff factor for sugar solution is 1, because sugar do not dissociate on ions.
Van't Hoff factor for aluminium nitrate solution is approximately 4, because it dissociates on four ions (one aluminium cation and three nitrate anions). So ΔT is four times bigger.

Don’t currently have a calculator with me but just use Avogadros constant (A) 6.02x10^24, in the equation n=N/A. Lower case n being the number of mol and upper case being the number of molecules (given).
