Answer 2

123.5 g will be the maximum mass of copper.

Given: CUO = 7.95 g
To find: Max mass of copper
Solution:

• Molecular mass of an fundamental is delineated as the total of common people of the details present in the particle.

• Molecular bulk is got by reproducing the protons and neutrons of an material accompanying the number of atoms in the particle and before increasing common people of all the materials in the fragment.
• The total of the tiny crowd of all atoms in a fragment, established a scale at which point the tiny crowd of hydrogen, element, nitrogen, and oxygen are 1, 12, 14, and 16, individually.
• For example, the microscopic bulk of water, that has two atoms of hydrogen and individual fragment of oxygen, is 18 (that is, 2 + 16).
  The balanced reaction for the decomposition of copper carbonate would be:

CuCO3 → CuO + CO2

1 mole of copper carbonate gives 1 mole of copper oxide

=> 123.5 g of copper carbonate gives 79.5 g of copper oxide.

Therefore, 12.35 g of copper carbonate will give 7.95 g of copper oxide.
