number of calcium ions present in 1 mole of calcium chloride solution

calcium carbonate

doesn't matter in this case. One mole of CaCl2 or CaCO3 contains exactly 1 mole of Ca++ ions.

To find the number of calcium ions present in 1 mole of calcium chloride solution, we need to determine the formula of calcium chloride and the number of calcium ions in one formula unit.

The formula of calcium chloride is CaCl₂. This means that each mole of calcium chloride contains one mole of calcium ions (Ca²⁺) and two moles of chloride ions (Cl⁻).

To calculate the number of calcium ions, we need to know Avogadro's number, which is approximately 6.022 x 10²³. This represents the number of particles (atoms, ions, molecules, etc.) in one mole of any substance.

Since calcium chloride contains one mole of calcium ions per mole of the compound, the number of calcium ions in 1 mole of calcium chloride is also 6.022 x 10²³.

Therefore, in 1 mole of calcium chloride solution, there are 6.022 x 10²³ calcium ions.
