If 20.00 mL of 0.2019 M HCl requires 39.63 mL of a NaOH solution for complete neutralization, what is the concentration of the NaOH solutions? How many significant figures are justified in the answer?

  • Chemistry -

    The equation is
    HCl + NaOH ==> NaCl + H2O

    mols HCl = M x L
    Convert mols HCl to mols NaOH from the equation.
    M(NaOH) = #mols/L.
    You have mols and L, solve for M.
    Post your work if you get stuck.
