- BNumber of milliliters which one mole of a gaseous substances occupies at NTP
- CNumber of molecules present in one gram molecular mass of a substance
- DAll of the above
✓
Answer
C. Number of molecules present in one gram molecular mass of a substance
Explanation: The number of entities present in 1 mol (gram molecular mass) of any substance is represented as Avogadro's constant or Avogadro's number denoted by NA. One mole contains exactly 6.02214076 × 1023 elementary entities.
