What is the atomic mass of carbon? The average atomic mass of carbon is 12.011. This is a weighted average based on three forms (isotopes) of carbon with different natural abundances. Carbon 12 has an atomic mass of 12.00 (carbon 12 is a special case because its mass is <i>defined</i> to be exactly 12 atomic mass units) and a natural abundance of 0.9893.

General Chemistry/Numbers Used to Describe Atoms The mass of an atom is measured in atomic mass units (amu). An atom's mass can be found by summing the number of protons and neutrons. By definition, 12 amu equals the atomic mass of carbon-12. Protons and neutrons have an approximate mass of 1 amu, and electrons have a negligible mass. Usually, a pure element is made up of a number of isotopes in specific ratios. Because of this, the measured atomic mass of carbon is not exactly 12.

How to Calculate Atomic Mass Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons. The atomic mass of the atom is the mass of the protons plus the mass of the neutrons, 6 + 7, or 13.

- A mole is the amount of matter that has a mass in grams equal to the atomic mass in amu of the atoms. Thus, a mole of carbon has a mass of 12 grams. The number of atoms in a mole is called the Avogadro number, Nav = 6.023  1023. Note that Nav = 1 gram/1 amu. Calculating n, the number of atoms per cm3 in a piece of material of density d (g/cm3).

Introduction Carbon-12 contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 (six protons plus six neutrons). Carbon-14 contains six protons, eight neutrons, and six electrons; its mass number is 14 (six protons plus eight neutrons). These two alternate forms of carbon are isotopes.

- For oxygen, a molecule consists of two oxygen atoms, and has a weight of 2 x 16 = 32. For carbon dioxide, there is one carbon atom (weight 12) and two oxygen atoms (mass 16 x 2) for a total of 44. This means that carbon dioxide should be about 44/32 = 1.375 times as heavy as an equivalent volume of oxygen.

Calculate the mass of a single atom of sulphur and a single molecule of carbon dioxide? Mass of a single atom of sulfar 1 mol of Sulfur is 32 grams of sulfur the mass is 32/avogadro's number in g 32/6.022*10^23=5.31×10^-23g Mass of a single molecule of carbon dioxide CO2 is 12.0 + 2x16.0 = 44.0 g/mole 44.0 g/mole x (1 mole / 6.022x10^23 molecules) = 7.31x10^-23 g / molecule.

- A mole is the number of carbon-12 atoms in exactly 12 grams of carbon-12. This number was determined by dividing the mass of a single carbon-12 atom into a 12 g mass of carbon-12. Since the mass of a single carbon-12 atom is tiny (1.99 x 10-23 g), the value of a mole comes out to be a huge number: 6.02 x 1023.

Avogadro's Number Example Chemistry Problem This number, 12.01, is the mass in grams of one mole of carbon. One mole of carbon is 6.022 x 10 23 atoms of carbon (Avogadro's number). This relation is then used to 'convert' a carbon atom to grams by the ratio: mass of 1 atom / 1 atom = mass of a mole of atoms / 6.022 x 10 23 atoms. Plug in the atomic mass of carbon to solve for the mass of 1 atom:

Mass Spectrometry Since a molecule of carbon dioxide is composed of only three atoms, its mass spectrum is very simple. The molecular ion is also the base peak, and the only fragment ions are CO (m/z=28) and O (m/z=16). The molecular ion of propane also has m/z=44, but it is not the most abundant ion in the spectrum.
