Ethylene diamine tetra-acetic acid (edta) is a water soluble compound that readily combines with metals such as calcium, magnesium, and iron. the molecular formula for edta is c10n2o8h16. one edta molecule complexes (associates with) one metal atom. a factory produces an aqueous waste that contains 20 mg/l calcium and collects the waste in 44-gallon drum. what mass of edta would need to be added to each drum to completely complexes all of the calcium in the barrel?
