Since the molecular formula of glucose is C6H12O6, it has 6 atoms of carbon element, 12 atoms of hydrogen element, and 6 atoms of oxygen element.
So, molecular weight of C6H12O6=(6×Atomic weight of corbon+(12×Atomic weight of hydrogen)+(6×Atomic weight of oxygen))
MC6H12O6=6×12.011+12×1.008+6×16.00
MC6H12O6=180.162 u
Final Answer: The molecular mass of glucose (C6H12O6) molecule is 180 u.
