Question

sophia is doing a science experiment and uses a compound with the chemical formula shown in the image: 2fe₂o₃. how many oxygen atoms are in this chemical formula? 3 oxygen atoms 4 oxygen atoms 6 oxygen atoms 2 oxygen atoms

Explanation:

Step1: Analyze the chemical formula

The chemical formula is \(2Fe_2O_3\). The sub - script of \(O\) (oxygen) in \(Fe_2O_3\) is \(3\), and the coefficient in front of \(Fe_2O_3\) is \(2\).

Step2: Calculate the number of oxygen atoms

To find the total number of oxygen atoms, we use the formula: \(\text{Number of }O\text{ atoms}=\text{Coefficient}\times\text{Sub - script of }O\).
Substitute the values: \(\text{Number of }O\text{ atoms}=2\times3 = 6\).

Answer:

6 oxygen atoms
