Question

How many atoms of Aluminum (Al) are in the following molecule(s):

4Al_3O_3
a) 4
b) 13
c) 30
d) 3

Answer 1

There are 8 Aluminum atoms in 4Al2O3 molecules.

Step-by-step explanation:

The student is asking how many atoms of Aluminum (Al) are in the compound 4Al2O3. The subscript next to Al indicates there are 2 Aluminum atoms within each Al2O3 molecule. Since there are 4 such molecules in the compound, we calculate the number of Aluminum atoms by multiplying 2 atoms by 4, giving us a total of 8 Aluminum atoms.
