To determine the number of oxygen (O) atoms in the molecular formula [tex]\(C_3H_4O_3\)[/tex], we need to analyze the given chemical formula.
The molecular formula [tex]\(C_3H_4O_3\)[/tex] specifies the number of each type of atom within a single molecule:
- [tex]\(C_3\)[/tex] indicates that there are 3 carbon (C) atoms.
- [tex]\(H_4\)[/tex] indicates that there are 4 hydrogen (H) atoms.
- [tex]\(O_3\)[/tex] indicates that there are 3 oxygen (O) atoms.
Therefore, the number of oxygen atoms in a molecule of [tex]\(C_3H_4O_3\)[/tex] is:
3
So, the correct answer is:
A. 3
