Hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

I know the formula for Potassium Alum is:

[tex]2KAl(SO_{4})_{2} * 12H_{2}O[/tex]

Now does this mean that there are 2 Moles of Potassium Alum or 24 moles of Potassium Alum if you include the 12 water molecules? I know when you calculate the molar mass of Potassium Alum, you need to add in the molar mass of the 12 water molecules.

Thanks
