A certain current liberated 0.504 g of hydrogen in 2 h. How many grams of copper can be liberated by the same current flowing for the same time in a copper sulphate solution? Given Atomic mass of Cu = 63.5

Options:

Answer:

Solution:

$\frac{W e i g h t o f C u}{W e i g h t o f H_{2}} = \frac{E q . w t . o f C u}{E q . w t . o f H_{2}}$

$\frac{Weightm of Cu}{0.504} = \frac{63.6/2}{1}$

$∴$ Weight of Cu $= 15.9 g$
