To find the number of households the power station can serve, we need to divide the total electricity generated by the power station by the average electricity used per household.
Dividing 2.496×10^10 kWh by 1.04×10^4 kWh gives us:
(2.496×10^10) / (1.04×10^4) = 2.4×10^(10-4) = 2.4×10^6
Therefore, the power station can serve approximately 2.4×10^6 households.
