| Calculate the amount of substance and the mass of copper, which is formed during the reduction of copper (II) oxide with a mass of 16 g with hydrogen.
The reduction reaction of copper (II) oxide with hydrogen is described by the following chemical reaction equation:
CuO + H2 = Cu + H2O;
Find the amount of substance in 16 grams of copper oxide.
M CuO = 64 + 16 = 80 grams / mol;
N CuO = 16/80 = 0.2 mol;
One mole of copper oxide forms one mole of copper.
N Cu = N CuO = 0.2 mol;
The mass of this amount of copper will be:
m Cu = 0.2 x 64 = 12.8 grams;
