Question- To ensure that do not provide customers with substandard product, the local steel mill has instigated a quality control program using flame AAS. two of the trace elements they wish to monitor, Al and Ti, form stable oxides. Is this a potential problem for the analysis and, if so, can something be done so the analysis can still be performed?
Not confident which formulas/units I require to solve something like this

A 0.1236-g sample of an unknown monoprotic acid was dissolved in 25.8 mL of water and titrated with 0.0680 M NaOH solution. The volume of base required to bring the solution to the equivalence point was 19.1 mL.
For each titration I need to calculate the moles of base needed to neutralize the acid sample. How do I go about doing this?
Problem- 20.0 mL sample of 0.150 M hypochlorous acid is titrated with 0.30 M NaOH. Calculate the pH when- a) write an equation for the reaction that occurs b) 0.00 mL of base has been added c) 5.00 mL of base has been added d) 10.0 mL of base has ..
