The amount of glyceryl triester of linoleic acid required to prepare 1208 g of sodium linoleate soap is ____ mol. (M.W. of sodium linoleate \({\mathrm{=302 \mathrm{~g} \mathrm{~mol}^{-1}}}\) )
1 2.66
2 1.33
3 3.02
4 0.26
Explanation:
No. of moles of sodium linoleate \({\mathrm{=\dfrac{1208}{302}}}\)\(=4 \mathrm{~mol}\) 1 mole glyceryl triester produces 3 moles of sodium linoleate ( \({\mathrm{\because}}\) Saponification reaction) \({\mathrm{=4 \times \dfrac{1}{3}=1.33 \mathrm{~mol}}}\) of glyceryl triester
