1. If 18.1mL of 0.800M HCl solution are needed to neutralize 5.00mL of a household ammonia solution, what is the molar concentration of the ammonia?
2.A volume of 100mL of a 0.380M HNO3 solution is titrated with 0.600M KOH. Calculate the volume of required to reach the equivalence point.
3.By titration, 15.0 of 0.1008 sodium hydroxide is needed to neutralize a 0.2053- sample of an organic acid. What is the molar mass of the acid if it is monopro-tic?
4.An elemental analysis of the acid indicates that it is composed of 5.89% H , 70.6% C , and 23.5% O by mass. What is its molecular formula?
