What volume of H(2) at STP is required t...

What volume of `H_(2)` at STP is required to reduce 0.795 g of CuO to give Cu and `H_(2)O`.

Text Solution

Verified by Experts

`H_(2)` reduces CuO according to the reaction
`CuO+H_(2)toCu+H_(2)O`
Moles of CuO = `0.795/79.5=0.01`
Since 1 mol. `of` CuO can be reduced by 1 mol. of `H_(2)`
0.01 mol of CuO is reduced by 0.01 mol. Of `H_(2)`.
Volume of `H_(2)=0.01xx22.4=0.2242`lits.
