Calculate the number of moles of EDTA required to titrate the water sample. (enter your answer with 3 significant figures)

0.000103
You are correct.
Your receipt no. is 163-5219 Previous Tries
The total hardness is due to one or a combination of Ca2+, Mg2+, and Fe2+ in your sample. It is convenient to express this hardness as though it was entirely due to Ca2+. Making this assumption, determine the number of moles of Ca2+ present in the bottled water sample titrated.
