ECE of copper is 3.3 10⁻⁷ ~kg / C . If 100 kWh energy is consumed at 33 V in a copper voltameter, then mass of copper liberated is

Options

  1. A3.6 kg
  2. B3.3 kg
  3. C1 kg
  4. D1 mg

Correct answer

A. 3.6 kg

Step-by-step solution

Mass of copper liberated aligned m & =z i t=z ( P V ) t & = (3.3 10⁻⁷ ) ( 100 36 10^5 33 ) = 3.6 kg aligned
