How many atoms are there in the formula of calcium carbonate CaCO3?

Answer 1

One. The Ca stands for Calcium, the C stands for Carbon, and the O stands for Oxygen. The number corresponds to the letter or element before it. In the case of Calcium Carbonate, the 2 comes after the Oxygen. This means that Calcium Carbonate is composed of 1 atom of Calcium, 1 atom of Carbon, and 2 atoms of Oxygen. Another example is this: H2O, This is two atoms of Hydrogen ( H ) bonded with one atom of Oxygen ( O ).

Answer 2

There are 5 atoms in the formula of calcium carbonate (CaCO3): 1 calcium atom (Ca), 1 carbon atom (C), and 3 oxygen atoms (O).

Answer 3

Calcium Carbonate, CaCO3 has 5 atoms. One of Calcium, one of Carbon, three of Oxygen.
