# 2) Protons and neutrons weigh 1/(6xx10^23) grams

Every, and we mean every proton and neutron  =1
6 x 1023
grams

An amazingly small number.

## Remember this:

1 proton = 1
6 x 1023
grams

and

1 neutron = 1
6 x 1023
grams

This is true, whatever the element, atom or molecule.

Examples

The weight of 1 mole of any proton =   6 x 1023 x 1
6 x 1023
grams

=          6 x 1023 x 1
6 x 1023
grams

=          1 gram

The weight of 1 mole of any neutron = 6 x 1023 x 1
6 x 1023
grams

= 6 x 1023 x 1
6 x 1023
grams

=          1 gram

That’s correct: the weight of any mole of protons or neutrons = 1 gram

WOW!
