What is the molecular mass of glucose (C6H12O6)? (Atomic masses: C = 12 u, H = 1 u, O = 16 u)
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 180 u
The molecular mass is the sum of the atomic masses of all the atoms in one molecule. A glucose molecule has 6 carbon, 12 hydrogen and 6 oxygen atoms.
Carbon: \(6\times12=72\) u
Hydrogen: \(12\times1=12\) u
Oxygen: \(6\times16=96\) u
Molecular mass \(=72+12+96=180\) u
