$4 g$ of copper was dissolved in $conc . {HNO}_{3}$ . The copper nitrate thus obtained gave $5 g$ of its oxide on strong heating the equivalent weight of copper is

Options:

Answer:

Solution:

$4 g$ of copper gave $5 g$ of its oxide means,

$1 g$ of oxygen combine with $4 g$ of copper.

$∵$ Eq. wt of oxygen $= 8$ ,

Therefore,

$8 g$ of oxygen combine with $= 4 \times 8 g$ of copper $= 32 g$

Hence,

Equivalent weight of copper $= 32$
