Lime is calcium carbonate, which is an ionic substance and does not exist as molecules. The formula unit gives the lowest whole number ratio of ions present in the substance, which is CaCO3. There are 5 atoms in one formula unit of lime; one calcium, one carbon, and three oxygen atoms.
There are 2 oxygen atoms in 1 molecule of oxygen.
There are four hydrogen atoms in an ethanal molecule, CH3CHO.
There are two atoms of hydrogen in a molecule of H2O2.
There are three atoms of chlorine in one molecule of sucralose.
The number of atoms in a molecule depends on its formula. The definition of a mole is approximately 6.022 x 10^23 entities (like atoms or molecules). For example, a molecule of water (H2O) contains 3 atoms - 2 hydrogen and 1 oxygen.
Calcium oxide (CaO) contain one atom of calcium.
There are 2 oxygen atoms in 1 molecule of oxygen.
A molecule of of water contain 3 atoms.
There are three oxygen atoms in the molecule HNO3.
