35 %(m/m) LiNO3 solution means 35 g of LiNO3 present in 100g of
soloution
                                                Â
5.2g of LiNO3 present in = 100*5.2/35 = 18.86 g of solution
20.0 %(m/m) KOH solution means 20g of KOH present in 100g of
solution
                                                Â
31.6g of KOH present in = 100*31.6/20Â Â = 158g of
solution
18 %(v/v) formic acid solution means 18ml of formic acid present
in 100ml of solution
                                                     Â
3.1ml of formic reaction in = 100*3.1/18Â Â = 17.22 ml of
solution
