What is the difference between molecular mass and molar mass

Posted by Sanyam Jain 4 years, 3 months ago

CBSE > Class 09 > Science

1 answers

Sia ? 4 years, 3 months ago

Basis	Molecular mass	Molar mass
Definition	Molecular mass is the mass of a molecule of a substance. It is also known as Molecular weight.	Molar mass is the mass of 1 mole of a substance or Avogadro’s number of the molecules of that substance.
Calculation	It is calculated as the ratio of the mass of one molecule of the substance to the mass of one Carbon-12 atom.	It is calculated as the ratio of the mass of a substance to the amount of the substance.
Mathematical representation	Molecular Mass = Mass of one molecule of substance / Mass of one C−12 atom × 1/12	Molar Mass = Mass of the substance / Amount of the substance
Unit	Atomic mass unit (amu)	Kg/Mole or g/mole
