Answer:
Malachite green has highest percentage of copper.
Explanation:
Azurite: 
Molar mass of Azurite = M = 344.67 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Azurite :

The percentage of copper in an azurite is 55.31%.
Malachite: 
Molar mass of Malachite = M = 221.12 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Malachite:

The percentage of copper in an malachite is 57.48%.
