i need help on a little part of the section.
The pecentage purity of an acid..
the three questions are
1 average titre,and molarity of acid
2 using calculated molarity determine conc of acid in g/m3
3 calc %age purity
i have worked part1 no problem but what does conc in g/m3 mean?i thought molarity was concentration.and how does that lead me to %age purity?
the key details are as follows
solid monoprotic acid mr 163.caculate ppurity with titration with naoh? (25cm3 portions of0.150 M NaOh)
7.1g of the acid was used,dissolved in water and made upto 250cm3.
the average titre was 22.25 and the molarity was 0.169 as asked in part 1...so how do i work out the rest??
thanks for your help..
