1. Write and balance the equation.
NaOH + HCl --> NaCl + H2O
2. calculate mols NaOH used. mols = M x L = ?
3. Convert mols NaOH to mols HCl. The coefficients in the balanced equation tell you that mols NaOH = moles HCl
4. Convert to M. M = mols HCl/L HCl
What is the HCl concentration if 71.9 mL of 0.350 M NaOH is required to titrate a 30.0 mL sample of the acid?
