Gram Molecular Mass

Gram Molecular Mass

The Molecular Mass of a Molecular substance expressed in grams is known as  Gram Molecular Mass .

It is also known as Gram Molecular Mass or gram atom or simply moles of substances.

 Formula

No of grams of molecular substance = Mass of molecular substance/Molecular mass of the substances

For example

• 1 gram molecules (moles ) of Hydrogen (H) = 2.016g of Hydrogen = 1 moles of Hydrogen molecules

• 1 gram molecules (moles ) of Carbon dioxide (CO₂) = 44.006g of Carbon dioxide  = 1 moles of Carbon dioxide molecules

•  1 gram molecules (moles ) of Nitric Acid (HNO₃) = 63.006g of Nitric Acid  = 1 moles of Nitric Acid  molecules

A moles of every  compound has 6.02x10^-23 molecules.
