determine the approximate molarity of a solution of NaOH prepared by diluting 10ml of 6M NaOH to a volume of 400 ml.
using the solution in the first part, 24.5ml of NaOH solution was required to neutralize 26.4ml of a .150M HCl solution. find the molarity of NaOH

  2. Approx molarity = 6 M x (10/400) or about 0.15 M
    exact molarity is
    M x mL = M x mL
    ?M x 24.5 mL = 0.15 x 26.4 mL
    solve for ?M.
