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.
