What is molecular maa |
| Answer» The molecular mass of a substance is the number of times the molecule of the substance is heavier than one-twelth the mass of an atom of carbon -12. Or, the molecular mass is equal to the sum of its atomic masses of all the atoms present in one molecule of a substance. For eg: Water (H2O)Atomic mass of H= 1 unitAtomic mass of O =16 unitsThe molecular mass of water = 2 × atomic mass of H+1 × atomic mass of O= 2 × 1 + 16 × 1= 18 units | |
