How many atoms of oxygen are in three molecules of CaCO3?

Answer 1

Three molecules of calcium carbonate (CaCO3) has nine(9) oxygens.

Think of 3CaCO3 = CaCO3 + CaCO3 + CaCO3.

Each molecule of CaCO3 has ;-

1 atoms of calcium (Ca)

1 atom of carbon (C)

3 atoms of oxygen (O3 = O + O + O).

So if one molecules of CaCO3 has 3 oxygens, then

three molecules of CaCO3 has 3 x 3 = 9 oxygens. The answer!!!!!

Answer 2

1 molecule of CaCO3 has 3 oxygen atoms. So, 3 molecule of CaCO3 will have 9 oxygen atoms.

Answer 3

9 atoms. Because 3 will multiply with 3 and becomes 9.

Answer 4

There are 9 atoms of oxygen in three molecules of CaCO3. Each molecule of CaCO3 contains 3 oxygen atoms, so when you have 3 molecules, you have a total of 9 oxygen atoms.
