`AlCl_3 rarr Al^(3+)+3Cl^-`


Mole ratio

`Al^(3+):Cl^(-) = 1:3`

So we would have 1/3 of `Al^(3+)`than the amount of chloride.

Amount of `Al^(3+) = 1/3*24 = 8`

So we have 8 moles of `Al^(3+)`


`AlCl_3:Cl^(-) = 1:3`

So we would have `1/3` of `AlCl_3`than the amount of chloride.

 

Amount of `AlCl_3 = 1/3*24 = 8`

So we have 8 moles of` AlCl_3` .

 

Molar mass of `AlCl_3 = 133.5g`


Mass of `AlCl_3 = 8*133.5 = 1068g`

 

So total mass of `AlCl_3` in the sample is 1068g.
