Can we say that, if any element has atomic mass equal to a unit and gram atomic mass a gram, then, a gram of that element will have no. of particles equal to Avagadro number?

Solution

Gram atomic mass is mass of any element (expressed in gram) of one mole of any atom.
Simply if atomic mass is expressed in gram, it is equal to gram atomic mass.

So if atomic mass is 1
Then 1 g of the element will contain Avogadro number of atoms.

Gram Atomic mass is just the atomic mass expressed in grams ...ie, atomic mass with gram as units. Our book says that gram atomic mass and gram atom are the same thing (similarly for gram molecule and gram molecular mass) . But later a formula is given that : Gram atom = mass in grams / Atomic mass [RAM].

There are questions also that use this formula ( similarly for gram molecule) in which we have to find the number of "gram atoms " in a given mass of substance.

So what is the real meaning of gram atom and the formula ( and is is similar for gram molecules) ?
