Gram atomic mass (Gram atom)

Gram atomic mass (gram atom)

The atomic mass of an element expressed in grams is called gram atomic mass. I s is known as gram atom or simply  mole.

 Formula

So number of gram atom (moles) of an element = massof the element/atomic mass of the element

For example

•                       1 gram atom (moles )of Hydrogen (H) =1.008 0f hydrogen (H)

•                         1 gram atom (moles )of Nitrogen (N) =14 0f Nitrogen (N)

•                         1 gram atom (moles )of Calcium (Ca) =40.00 0f Calcium (Ca)

Reason

The reason is that atomic mass of hydrogen is 1.007µ, of nitrogen is 14.00µ and calcium is 40.00 µ . so  one moles of every element has 6.02x10^-23
