In the context of a chemical formula, the correct term that indicates how many molecules are present is coefficient. Coefficients are the numbers placed in front of chemical formulas that indicate the quantity of molecules or moles of that substance.
For example, in the equation 2 H₂O, the "2" is the coefficient, indicating that there are 2 molecules of water (H₂O).
- Subscript refers to the number of atoms of an element in a molecule, not the number of molecules.
- Product typically refers to the substances formed in a chemical reaction.
- Chemical symbol represents a specific element (like H for hydrogen or O for oxygen) but does not indicate the number of molecules.
So the correct answer is coefficient.
