What is the total number of mole of atoms in 1 mole of Al2(CO3)3?
You have 2 mols Al
and 3 mols C
and 9 mols O.
To find the total number of moles of atoms in a compound, we need to calculate the sum of the moles of each type of atom present in the compound.
In Al2(CO3)3, we have 2 atoms of Aluminum (Al), 1 atom of Carbon (C), and 3 atoms of Oxygen (O) within each formula unit.
First, let's calculate the moles of Aluminum (Al):
The molar mass of Aluminum (Al) is approximately 26.98 g/mol. Since there are 2 Al atoms in each formula unit of Al2(CO3)3, the total mass of Al would be 2 * 26.98 g/mol = 53.96 g/mol.
Next, let's calculate the moles of Carbon (C):
The molar mass of Carbon (C) is approximately 12.01 g/mol. Since there is only 1 C atom in each formula unit of Al2(CO3)3, the total mass of C would be 1 * 12.01 g/mol = 12.01 g/mol.
Finally, let's calculate the moles of Oxygen (O):
The molar mass of Oxygen (O) is approximately 16.00 g/mol. Since there are 3 O atoms in each formula unit of Al2(CO3)3, the total mass of O would be 3 * 16.00 g/mol = 48.00 g/mol.
Now, we can sum up the moles of each type of atom:
Moles of Al = 53.96 g/mol / 26.98 g/mol = 2.00 mol
Moles of C = 12.01 g/mol / 12.01 g/mol = 1.00 mol
Moles of O = 48.00 g/mol / 16.00 g/mol = 3.00 mol
Therefore, in 1 mole of Al2(CO3)3, there are a total of 2.00 moles of Aluminum, 1.00 mole of Carbon, and 3.00 moles of Oxygen atoms.
