Calculate the mass of the formed copper oxide (2) CuO, if 10 mol of copper is oxidized with atmospheric oxygen.

Metallic copper reacts with oxygen to form oxide. The reaction is described by the following chemical equation:

Cu + ½ O2 = CuO ↑;

N Cu = 10 mol;

The same amount of copper oxide can be obtained.

Find the weight of the copper oxide. To do this, multiply the amount of substance by the weight of 1 mole.

M CuO = 64 + 16 = 80 grams / mol;

m CuO = 10 x 80 = 800 grams;
