How can one find the percent abundance of an atom when 3 isotopes and the average atomic mass are given? How to calculate atomic mass of isotopes What is the difference between isotope abundance and isotope mass? How do you calculate the atomic number of isotopes?
I got it - number density, not number. The question was number, not density, and as mentioned, number is problematic as the universe may be infinite.FAQ: How Do We Calculate the Number of Atoms in the Universe? How many atoms are estimated to be in the observable universe?

Each element on the periodic table has an atomic mass -- an approximation of the mass of a single atom of that element. Because atoms are so small, a specific unit is used to measure the mass of small quantities of atoms. Very large quantities of atoms a

An atom has a neutral charge, so the positive and negative charges are equal to each other. The atomic number is also the number of electrons. Step 3 Calculate the number of neutrons by taking the mass number and subtracting the number of protons found in the nucleus. The mass number is...
