    1) The number of moles of jojoba oil wax ester = mass/molar mass = 5.0g/618.07g/mol = 8.09*10^-3 mol

    Hence we need at least the number of moles of NaOH required = 2*8.09*10^-3 = 16.18 * 10^-3 mol

    We have 1.0mol/1000mL solution. Hence volume of 1.0M NaOH solution = (16.18*10^-3) / (1/1000) = 16.18mL

    Thus the answer is 16mL.
