2. Atomic Mass Unit (abbreviations: amu, or u): also known as dalton (symbol: Da), is a standard unit of mass that used on an atomic or molecular scale (atomic mass).One unified atomic mass unit is about the mass of one nucleon (either a single proton or neutron) and equivalent to 1 g/mol. Kilogram (abbreviations: kg, or kgm): is a SI (metric) system unit of mass (IPK, also known as 'Le Grand K.

Why is the atomic mass unit (amu), rather than the gram, used to express atomic mass?

1 Answer

Because atoms are ridiculously small.

Atomic Mass Unit To Kg Per

And the #'amu'# is numerically equivalent to the #'g/mol'#. For instance, if I were to be so lucky as to isolate #'1 atom'# of #'N'#, it would have a mass of

#14.007 cancel'amu' xx (1.6605 xx 10^(-24) 'g')/(cancel'1 amu')#

#= ul(2.326 xx 10^(-23) 'g')#

which is immeasurably small. We don't care for masses that small because we physically can't see or measure it. Instead, we care for masses we can touch, like #'1.000 g'# or #'12.50 g'#.

And that involves:

#1.000 cancel'g N' xx cancel'1 mol N'/(14.007 cancel'g N') xx (6.022 xx 10^23)/(cancel'1 mol')#

#= ul(4.299 xx 10^22 'N atoms')#

#12.50 cancel'g N' xx cancel'1 mol N'/(14.007 cancel'g N') xx (6.022 xx 10^23)/(cancel'1 mol')#

#= ul(5.374 xx 10^23 'N atoms')#

You can clearly tell that this number of atoms is impossible to count. And so Avogadro's number, #6.022 xx 10^23 'mol'^(-1)#, was invented to describe this many particles...

#4.299 xx 10^22##'N atoms' xx ('1 mol')/(6.022 xx 10^23)#

#=##ul'0.0714 mols N'#

#5.374 xx 10^23##'N atoms' xx ('1 mol')/(6.022 xx 10^23)#

#=##ul'0.8924 mols N'#

And as you can see, these numbers look much nicer and more physically useful.
