A current of 9.65 A is drawn from a Daniell cell for exactly one hour. If molar masses of Cu and Zn are 63.5 g `mol^(-1)` and 65.4 g `mol^(-1)`, respectively, the loss in mass at anode and gain in mass at cathode respectively are

Options

A. 11.43g,11.77g
B. 11.77 g, 11.43 g
C. 22.86 g, 23.54 g
D. 23.54 g, 22.86 g

Answer

C

Explanation

Quantity of electricity passed =9.65 x 60 x 60 c
Amount of Zn oxidized or `Cu^(2+)` reduced =`(60xx60)/(2xx1000)` mol
Mass of zn lost =`(65.4xx60xx60)/(2xx1000)g=11.77g` and mass of cu gain =`(63.5xx60xx60)/(2xx1000)g=11.43 g`
