I cannot figure out the equation and answer to the following. Can someone help please.
A 25.0 mL solution of HCl has been spilled. It took 21.8 mL of saturated 2.5 M NaOH to neutralise the acid. What was the molar concentration of the acid?

  • Chemistry -

    HCl + NaOH ==> NaCl + H2O

    mols NaOH used = M x L = ?
    mols HCl neutralized = mols NaOH
    M HCl = mols HCl/L HCl

    I think this was asked before:
