Answer:
Mole percent of water in azeotrope is 69%
Explanation:
Clearly, the azeotrope consists of water and perchloric acid.
So, 72% perchloric acid by mass means 100 g of azeotrope contains 72 g of perchloric acid and 28 g of water.
Molar mass of water = 18.02 g/mol and molar mass of perchloric acid = 100.46 g/mol
So, 72 g of perchloric acid = of perchloric acid = 0.72 mol of perchloric acid
Also, 28 g of water = of water = 1.6 mol of water
Hence total number of mol in azeotrope = (1.6+0.72) mol = 2.32 mol of azeotrope
So, mole percent of water in azeotrope = [(moles of water)/(total no of moles)]%
Mole percent of water = % = 69%

Explanation:
The fatty acids form ester C-O bonds with the OH groups of glycerol and the phosphoric acid forms phosphate P-O bonds.
The phosphate also forms P-O ester linkages with the OH groups in other alcohols such as choline.
The structure below shows the phospholipid with two saturated C₈ fatty acids and the phosphate group.
