Per NCERT, what is MOLECULAR MASS — and how is it calculated?
AMolar mass divided by Avogadro's number
BEmpirical formula mass divided by n
CSum of atomic masses of all atoms in a molecule (multiply each element's atomic mass by number of atoms, then add)
DAverage atomic mass
Answer & Solution
Correct answer: C. Sum of atomic masses of all atoms in a molecule (multiply each element's atomic mass by number of atoms, then add)
Per NCERT §1.7.3, molecular mass = Σ(atomic mass × number of atoms). The other options misstate.
