A steady current of `1.5 A` flows through a copper voltameter for 10 min. If the electrochemical equivalent of copper is `30 xx 10^(-5) gC^(-1)`, the mass of copper deposited on the electrode will be

Options

A. 0.27 gm
B. 0.40 gm
C. 0.50 gm
D. 0.67 gm

Answer

A

Explanation

`m=ZIt=(30xx10^(-3))(1.5x)10xx60)=0.27`gm
