C = n/X = (1.XXXXX mmol)/(XX.50 mL) = X.0765 mol/X
The XXXXXXXX of XXX XXX solution XX X.XXX M.
X. XXX addition XX the XXXXX will XXX XXXXXXXXX since the amount of XXXXX XXXX was XXXXX is XXXXX. The concentration of XXX titrated sample "C2" XXX XX calculated as XXXXX, XXX then the XXXXXXXX XXXXXXXX XXX be applied to find the XXXXXXXX molarity "C1" of XXX HCl XXXXXX:
C1 = C2V2/XX = XX(40.XXXX/XX.XX XX)
