Contents The atomic mass is the mass of a single atom of the element. It is measured in units in which an atom of carbon weighs exactly 12. On this scale, the atomic mass of hydrogen is approximately 1, that of helium is 4, and so on. In 1869, Dmitri Mendeleyev noticed regularites in the chemical properties of the elements. He arranged the list of elements into the periodic table of the elements.

How do you find the mass in grams of moles of a certain element? However make sure you get the atomic MASS not atomic NUMBER. If unsure, the mass is the bigger of the two. So for Neon: moles of neon = 125 Relative atomic mass of neon = 20 Rearranging formulma above gives: moles/relative atomic mass=mass in grams 125/20=6.25 grams Hope this helps.Source(s): Tim Burr · 7 years ago. need help finding the mass in grams of x number of moles of x Example: determine the mass in grams of 125 moles of neon I have no periodic table to refer to so I have no idea and even with one I have no idea Thanks. Update: Can anyone help explain it in easier terms to understand.

What Is 1/12 the Mass of a Carbon-12 Atom? According to HowStuffWorks, an atomic mass unit is defined as the mass of a single proton or neutron. Hydrogen, the lightest element, has an average mass of 1.00794 amu. A carbon-12 atom is made up of six protons and six neutrons, hence 12 atomic mass units. The mass of the electron is considered negligible, therefore electrons are not counted in measuring an atom's atomic mass.

What is Atomic Mass? - Definition & Examples The atomic mass for an atom of hydrogen is one dalton, which is calculated from the lone proton. Remember, electrons are too small to be considered in the atomic mass. Helium is the second lightest element, and is larger than hydrogen. It consists of two protons and two neutrons. Because protons and neutrons are approximately the same size, the atomic mass of a helium atom is four daltons. Let's look at a larger atom. Barium has an atomic mass of 137 daltons.

How Do You Weigh an Atom? When discussing atoms, many people use atomic weight and atomic mass interchangeably, even though they aren't quite the same thing either. Atomic mass is defined as the number of protons and neutrons in an atom, where each proton and neutron has a mass of approximately 1 amu (1.0073 and 1.0087, respectively). The electrons within an atom are so miniscule compared to protons and neutrons that their mass is negligible.
