Answer Details

The electrochemical equivalent of a metal is the amount of the metal deposited per unit charge passed through an electrolyte. In this case, the electrochemical equivalent of the metal is given as 1.3 x 10^-7 kgC^-1. To find the mass of the metal deposited by 2.0 x 10^4 C of electricity, we can use the formula: mass = (charge x electrochemical equivalent) Substituting the values given, we get: mass = (2.0 x 10^4 C) x (1.3 x 10^-7 kgC^-1) = 2.6 x 10^-3 kg Therefore, the mass of the metal deposited by 2.0 x 10^4 C of electricity is 2.6 x 10^-3 kg. So, the correct option is: 2.6 x 10-3kg.
