what is the difference between molar mass and equivalent mass?
Ex: The molecular mass of oxygen is 32. This means that oxygen is 32 times heavier than 1/12th of the mass of carbon 12. Equivalent mass is defined as the number of parts by mass of the substance which combine or displace 1.008 parts by mass of hydrogen or 8 parts by mass of oxygen or 35.5 parts by mass of chlorine.
