2 Al(CO₂)₃ number of atom

The chemical formula Al(CO₂)₃ suggests that there is one aluminum atom (Al) present and three carbonate ions (CO₂), which are composed of one carbon atom (C) and two oxygen atoms (O).

So, the total number of atoms in 2 Al(CO₂)₃ is as follows:

Number of Aluminum atoms (Al): 2 x 1 = 2

Number of Carbon atoms (C): 2 x 1 x 3 = 6

Number of Oxygen atoms (O): 2 x 2 x 3 = 12

Therefore, in 2 Al(CO₂)₃, there are a total of 2 Aluminum atoms, 6 Carbon atoms, and 12 Oxygen atoms.
