Question

What volume of H2 at STP is required to reduce 0 795 of
CuO to give Cu and H2O

Akanksha C. · Accepted Answer

Dear Student,

Reaction : CuO + H2 ------> Cu + H2O

copper oxide and hydrogen gas react in 1:1 ratio

Mass of 1 mole of copper oxide = 79 5 g

Moles of copper = given mass/ molar mass = 0 795/ 79 5 = 0 01
mole

1 mole of copper oxide react with 1 mole of Hydrogen gas
And we know that 1 mole of any gas at STP = 22 4 l
so, Volume of hydrogen gas which is required to reduced 0 795 g of
CuO = 22 4 X 0 01 = 0 224 l
