To convert from formula units to moles, you need to divide by Avogardo's constant. And then remember that there will be 2 moles of Cl for every 1 mole of MgCl₂.
1.81*10^24 formula units MgCl₂ * (1 mole MgCl₂/6.022*10^23 formula units MgCl₂) * (2 moles Cl/1 mole MgCl₂) = 6.01 moles Cl
There are 6.01 moles of Cl atoms in 1.81*10^24 formula units of MgCl₂.
<h2>Dissolving process</h2>
Explanation:
Steps in the dissolving process are as follows:
- the solvent molecules are attracted to the molecules at the surface of the solute particles.
- the solvent molecules surround the solute molecules or ions.
- the solute molecules are carried into the solution.
- the solute is mixed with the solvent.
A homogenous mixture of solid and liquid is called a solution. The liquid that dissolves the solid is called solvent while the solid that gets dissolved is called solute.
A mixture whose components cannot be identified easily is called homogenous mixture e.g. sugar powder and salt, tap water, air etc.
