Glucose is a simple sugar with the molecular formula C6H12O6.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 = 16
 
Molar mass of C6H12O6 = 6×12+1×12+6×16 = 72+12+96 = 180
 
So, the molar mass of glucose is 180g
 
(A)  180g is correct answer.
