50.0 mL of an unknown HCl solution was titrated with 0.449 M NaOH. To reach the equivalence point, 38.4 mL of the NaOH was used. What was the concentration of the HCl?

Answer 1

NaOH + HCl ==> NaCl + H2O
mols NaOH = M x L = ?
mols HCl = mols NaOH since the ratio in the equation is 1:1.
Then M HCl = mols HCl/L HCl. YOu knowL and mols, solve for M
