Answer:
Malachite green has highest percentage of copper.
Explanation:
Azurite: [tex]2CuCO_3.Cu(OH)_2[/tex]
Molar mass of Azurite = M = 344.67 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Azurite :
[tex]Cu\%=\frac{3\times 63.55 g/mol}{344.67 g/mol}\times 100=55.31\%[/tex]
The percentage of copper in an azurite is 55.31%.
Malachite: [tex]CuCO_3.Cu(OH)_2[/tex]
Molar mass of Malachite = M = 221.12 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Malachite:
[tex]Cu\%=\frac{2\times 63.55 g/mol}{221.12 g/mol}\times 100=57.48\%[/tex]
The percentage of copper in an malachite is 57.48%.
