Q. Calculate the mass of one atomic mass unit in grams.

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) ?

Q. Assertion :Actual atomic mass is greater than mass number. Reason: Mass of protons and neutrons is measured in daltons or atomic mass unit (u) but the mass of each neutron and proton is slightly greater than 1 dalton.
