To ensure efficient transesterification of the Jojoba Oil wax esters to methyl ester biodiesel, at least two molar equivalents of sodium methoxide is used. What volume of 1.0M sodium methoxide in methanol solution must be used for efficient transesterification of of 5.0g Jojoba oil

Respuesta :

mirianmoses

Answer:

Explanation:

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.
