solutionandthevolumeofsolutionneeded.Usetheformula:

MassofPAC(g)=Concentration(%)Volumeof

solution(mL)Densityofsolution(g/mL)。

Note:Thedensityofa10%polyaluminiumchloride

solutionisapproximately1.25g/mL.

2.Addwatertothecontainer:Fillthecontainerwith

thedesiredvolumeofwater,leavingenoughspaceforthe
