Question

Glucose +5(CH,CO), →X + 5 molecules of acetic acio
The increase in molecular mass of glucose on forming X
in the above reaction is
(1) 210 (2) 135 (3) 215
(4)220​

Answer 1

ANSWERGlucose is a simple sugar with the molecular formula C 6 H 12 O 6 .It is soluble in water and acetic acid.Molar mass of glucose can be calculated by the sum of relative atomic masses of atoms in a molecule of a substance.As we know, atomic mass of C = 12 atomic mass of H = 1 atomic mass of O = 16Molar mass of C 6 H 12 O 6 = 6×12+1×12+6×16 = 72+12+96 = 180So, the molar mass of glucose is 180g. 180g is correct answer.
