Copper is a divalent metal . The value of its electrochemical equivalent is `3.29 xx 10^(-4)` g. Its atomic mass is

Options

A. 31.74 g
B. 63.5g
C. 126.9g
D. 15.87 g

Answer

B

Explanation

Electrochemical equivalent , `Z=(E)/(96500)`
` or 3.29 x 10^(-4)=(E)/( 96500)`
`:. E=31.74`
Atomic mass `= 2 xx E " " [ :' Cu " is divalent".]`
`= 2 xx 31.74 =63.49g `
