30 kg / 108 = 0.27777777778 kg per book.
So for 150 books: 150 * 0.27777777778 kg = 41.666666667 kg.
And for 29kg of books: 29 / 0.27777777778 kg = 104.4 books.
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.

no youre thinking of molar mass and atomic weight although you use avogadro's number to find molar mass
On the periodic table it is the number on the bottom of the element.If you know the amount of neutrons you can add it to the number of protons to find the atomic mass NUMBER, which is a good approximate of the atomic mass.Potassium (isotope 39), 19K(39), has 19 protons and 20 neutrons19 + 20 = 39 atomic mass NUMBER, its atomic mass is 39.10 a.m.u.
If the bottles are identical, then the bottle of waterhasmore mass in it than the bottle of steam.
Mass production
The atomic number of the isotopes of an element is identical; the mass number is different.
Mass number = Number of protons + number of neutrons

Isotope
Mass number = Number of Protons + Number of Neutrons
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
Usually, large numbers of identical products are made on a production line or assembly line.
To find the number of neutrons in an atom you subtract the atomic mass fromthe mass number
Number of neutrons = Mass number - Number of protons
Number of neutrons = Mass number - Number of protons
