If the Earth has a mass of 5.98 X 1024 (which seems likely to be what the questioner meant, since the Earth clearly has a mass of much more than 6 kilograms), the average mass of the atomic units that make up the Earth is 40 amu, and 1 amu = 1.6605402 X 10-27 kg (which seems likely to be what the questioner meant, since the number as given is a negative number and therefore can not be correct for a mass), the answer is:
5.98 X 1024/[(40)(1.6605... X 10-27)] = 1.435 X 1052 atoms.
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
The average atomic mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance. The atomic mass listed on the periodic table is the weighted average of all naturally occurring isotopes of the element. So, they are essentially the same thing, with the average atomic mass being a more specific term.
Carbon has an average atomic mass of about 12.
Magnesium has an average atomic mass of 24.31 amu.
Atomic mass refers to the mass of an individual atom of a specific element, while average atomic mass is the weighted average of the masses of all the isotopes of an element, taking into account their relative abundance in nature. Average atomic mass is usually listed on the periodic table, while atomic mass is specific to a single isotope.
bcause whwn we are talking about atoms we use atomic unit
The average atomic mass of an element is the average of the atomic masses of its isotopes (that is a weighted average). You have to take into account the abundance of each isotope when they do your averaging.
What is weighted average atomic number
The SI unit for mass is the kilogram - whether for an atomic particle of for a galaxy.

The average atomic mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance.

The average atomic mass of Lithium (Li) is 6.941.
The average atomic mass for titanium is 47.867.
Carbon has an average atomic mass of about 12.
Magnesium has an average atomic mass of 24.31 amu.
The weighted average of the atomic masses of an element's naturally occurring isotopes is called the atomic mass. This value takes into account the abundance of each isotope in nature when calculating the overall average atomic mass of the element.
