A lab worker makes up 1000.00mL of a KOH solution but forgets to record teh mass of teh dissolved KOH. Whe 42.82 mL of the KOH solution is titrated with 1.209 M solution of HCL 28.35mL of the acid solution are required to reach the equivalance point. What is the concentration of the KOH solution and what mass of KOH was dissolved?
