How many pounds of alum sulfate do I need to buy to make 8000 gallons of 48% solution.
Thank you

You do it the same way you did the 25% NaOH solution. You will need to determine the density of 48% alum sulfate first.

I did review that answer before I posted , but I don't know how to calculate the solution weight of 25% NaOh or 48% Aluminum Sulfate

Alum sulfate solution
Can you figure weight of solution with specific gravities?

That's how much anhydrous aluminum sulfate you will need to use. If you are purchasing the octadecahydrate, multiply that number by the ratio (666/342). If purchasing the hexadecahydrate multiply it by the ratio (648/342).
