What is the molar mass (g/mol) of unknown carbonate number in the titration of Hcl & Naoh
Average titre of Naoh (1.023M) is 22.5 ml.
Initial amount of acid acid (1.062M) before reacted with carbonate is 0.02655 mol
Mass of carbonate = 0.466
The hydrogenation of Oleic acid to a steric acid. we used 10% pd/c, ammonium formate, mentanol, dichloromethane, 95% ethanol, and 1M sulfuric acid to get steric acid.
