About one gram....

Explanation:

The number #6.02xx10^23# is near enuff to #N_A#, the #"Avocado number"#, which is the link between the submicro world of atoms and molecules, to the macro world of grams and litres, that which we can conveniently measure in the lab.

It is a fact that #underbrace(6.022xx10^23)_"Avogadro's number"# #""^1H# ATOMS, each with a nominal mass of #1*"amu"# have a collective mass of #1*g#.

This definition is worth spending some time on, because it underlies every problem in chemical equivalence....
