Per NCERT, MOLAR MASS of a substance is defined as which value?
AMass of one atom of carbon-12
BMass of one molecule
CMass of one electron
DThe mass of one MOLE of the substance in grams — numerically equal to atomic/molecular/formula mass in u
Answer & Solution
Correct answer: D. The mass of one MOLE of the substance in grams — numerically equal to atomic/molecular/formula mass in u
Per NCERT §1.8, molar mass (g/mol) is numerically equal to atomic/molecular/formula mass (u).
