Question

The formula of acetic acid is C2H4O2. How many atoms is acetic acid composed of?A. 4B. 8C. 6D. 3

Answer 1

Acetic acid, with the formula C2H4O2, is composed of 8 atoms in total, which includes 2 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms.

Step-by-step explanation:

The formula of acetic acid is C2H4O2. To determine how many atoms acetic acid is composed of, we simply add up the number of each type of atom present in the molecule. According to the formula, there are 2 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms. This gives us a total of:

2 (Carbon) + 4 (Hydrogen) + 2 (Oxygen) = 8 atoms.

Therefore, the correct answer is B. 8.

Answer 2

8 atoms

Procedure

The number of atoms can be calculated by looking at the chemical formula and remembering that the subscript means the number of atoms of that particular element.

In this case, we have the formula C₂H₄O₂, therefore the number of atoms are calculated as follows:

Number of atoms = 2+4+2= 8 atoms
