Trimyristin can be synthesized from glycerol and tetradecanoic acid in 87% yield

Question

Trimyristin can be synthesized from glycerol and tetradecanoic acid in 87% yield. If 25.00 g of trimyristin is needed, what amount of both starting materials (in grams) would need to be used in order to provide the needed amount of trimystin? *Watch sig fig/units. Any help on this problem would be very much appreciated.

Explanation / Answer

1gycerol + 3 tetradecanoic acid ---> 1 trimyristin, , 25 gm product = 25/723.16 = 0.03457 , since yield is 87% , moles of gycerol required = ( 100/87) x 0.03457 =0.03974, moles of tetradecanoic acid = 3 x0.03974 = 0.119 , mass of glycerol needed = 0.03974 x 92 = 3.656 grams , mass of tetradecanoic acid = 0.119 x 228.37 = 27.176 grams
