In the last part where u have to calc. The percentage they used the conc. Of mg2+ we found out in the part above divided by the total (0.05) in sea water and took its percentage they considred it to be of the mg 2+ which was left behind,then substracted it from 100 to find the one which was extracted.Shouldnt the one without substracting it from 100 be of extracted coz mgoh2 is precipitated?
