10L of hard water required 5.6g of lime for removing hardness. hence temporary hardness in ppm of cac03.
The answer 1000ppm
I really want all tutors to solve it form clearly step by step.
Thank a lot

hard water? Do you mean has dissolved calcium carbonate? Then why would one add lime, lime is the source of hardness.
I have no idea what this problem statement means
