Question

how many oxygen atoms are in this chemical formula? 4 oxygen atoms 3 oxygen atoms 6 oxygen atoms 2 oxygen atoms

Explanation:

Step1: Analyze the sub - script for oxygen

In the formula \(Fe_2O_3\), the sub - script for oxygen (\(O\)) is \(3\).

Step2: Consider the coefficient

The coefficient of the entire formula \(Fe_2O_3\) is \(2\). To find the total number of oxygen atoms, we multiply the coefficient by the sub - script of oxygen. So, the calculation is \(2\times3\).

Answer:

6 oxygen atoms
