Answer:
19 atoms
Step-by-step explanation:
We are given the compound as;
5Al(C2H3O2)_2
To find the number of atoms, we will find the number of atoms of each individual element and add up.
Al has 5 atoms
C has (2 × 2) = 4 atoms
H has (3 × 2) = 6 atoms
O has (2 × 2) = 4 atoms
Thus;
Total number of atoms = 5 + 4 + 6 + 4 = 19 atoms
