Given the chemical formula 6Al2O3, how many total atoms of aluminum and oxygen are present?

• A. 36 atoms
• B. 18 atoms
• C. 30 atoms
• D. 24 atoms

Answer: (C)

Verified step by step guidance

1. Identify the number of formula units given: here, it is 6 units of Al\_2O\_3.
2. Determine the number of atoms of each element in one formula unit. In Al\_2O\_3, there are 2 aluminum (Al) atoms and 3 oxygen (O) atoms per formula unit.
3. Calculate the total number of aluminum atoms by multiplying the number of formula units by the number of aluminum atoms per unit: \$6 \times 2$.
4. Calculate the total number of oxygen atoms by multiplying the number of formula units by the number of oxygen atoms per unit: \$6 \times 3$.
5. Add the total aluminum atoms and total oxygen atoms together to find the total number of atoms present: \((6 \times 2) + (6 \times 3)\).
