One. If Ca had a 2 (or more) before it or a small 2 (or more) after it towards the bottom, then there would be more than 1. Since there are no numbers before or after Ca, there is only one Ca atom.

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

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!!!!!
