Please solve this sum..
Dear student,
Cellulose is made up of glucose units by the condensation method of polymerisation.
That means two glucose molecule bind to form one glycosidic bond by the loss of one glucose molecule.
Therefore, the number of water molecules removed is one less than the number of glucose unit.
One mole of glucose weighs 180 g.
Therefore, on complete hydrolysis, the glucose units will be formed from X.
Therefore, the number of glucose unit formed =1620/180 = 9.
Therefore, there were 8 water molecules required to break 8 glycosidic bond.
The molar mass of water is 180 g/mol.
Therefore, the weight of the cellulose will be 1620-8x18=1476 g,
Hence, the correct answer is A.
