How Many Atoms of each Element are Found in 2ai2o3

To determine the number of atoms of each element in 2Al2O32 \text{Al}_2\text{O}_32Al2​O3​, let’s break it down step by step.

1. Identify the elements and their quantities in the formula unit:
   • In one formula unit of Al2O3\text{Al}_2\text{O}_3Al2​O3​:
     • There are 2 aluminum (Al) atoms.
     • There are 3 oxygen (O) atoms.
2. Multiply by the coefficient:
   • The coefficient 2 indicates that there are 2 formula units of Al2O3\text{Al}_2\text{O}_3Al2​O3​.
3. Calculate the total number of atoms:
   • Aluminum (Al):
     • $2\times 2=4$ aluminum atoms.
   • Oxygen (O):
     • $2\times 3=6$ oxygen atoms.

Final Answer:

In 2Al2O32 \text{Al}_2\text{O}_32Al2​O3​, there are:

• 4 aluminum (Al) atoms.
• 6 oxygen (O) atoms.
