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?
Attached is a detailed explanation... View the full answer
- Mass dissolved = (molarity x volume) x molar mass of KOH = 8 x 1 x56.1056 = 499.1 g
