A carbon-12 atom has a mass of 12 Atomic Mass units. This means that a mole (6.02 * 10^23 atoms) would have a mass of 12 grams. So 1/12 of a mole of carbon-12 would have a mass of one gram. So (6.02 * 10^23) / 12 should give you your answer.

1 mol of carbon atoms is 12.011g.

Mass of 1 atom of carbon = 12.011/(6.02x1023) = 2.0 x 10-23g

What tells you how heavy an element's atoms are compared with atoms of other elements?

This is the relative atomic mass, which compares other atoms to the mass of I atom of the isotope carbon-12.


How do you find neutrons in an element?

In order to find the number of neutrons in the atoms of an element, you must specify the isotope that you are interested in. Isotopes are specified according to their mass number. For example carbon-12 is the isotope of carbon that has a mass number of 12, and carbon-14 is the isotope of carbon that has a mass number of 14. All atoms of the same element, regardless of mass number, have the same number of protons, which is the element's atomic number. To determine the number of neutrons in an isotope, you subtract the atomic number from the mass number. For example, the atomic number of carbon is 6, which means that all carbon atoms contain 6 protons in their nuclei. So, to find the number of neutrons in a carbon-12 atom, subtract 6 from 12, and you get 6 neutrons in the atoms of carbon-12. To find the number of neutrons in a carbon-14 atom, subtract 6 from 14, and you get 8 neutrons in the atoms of carbon-14.


What is the mass of 7.8 x 1018 carbon atoms?

3.011 x 1023 atoms of carbon will weigh about 6 grams One mole of carbon atoms weighs 12.011 grams, and there are 6.022 x 1023 atoms in a moles. So you have half as many atoms, so the mass would be half as much or 6.0055 grams to be precise.


How many neutrons does the isotope carbon have?

Most carbon atoms have 6 neutrons, but a small fraction of them have 7 neutrons (to make carbon-13 isotope atoms) or 8 neutrons to make carbon-14 isotopes. Radioactive carbon atoms with other numbers of neutrons can be made in nuclear reactions.

Does mole of carbon atoms have a different mass than a mole of sulphur atoms?

Yes. To find out the mass of a mole of atoms of any given element, see the atomic mass given on the periodic table. A mole of carbon atoms has a mass of 12.011 grams. A mole of sulfur atoms has a mass of 32.06 grams.


What relationships are needed to convert 1.5 grams of carbon to the number of carbon atoms?

molar mass and Avogadro's number


What is the mass of 1 mole of carbon atom?

We use the equation: Mass = Number of moles * Molecular or atomic mass Since the number of moles is 1 ("one mole of carbon-12 atoms") and the atomic mass of carbon-12 atoms is 12, hence the mass would be 12 grams. Note that the unit grams (g) is used here, as it is the SI unit for mass measurement. I hope this is useful! :)


What is the atomic mass of an element and how is it determined?

The atomic mass of a radioactively stable element is defined as the mass, usually measured in grams, of Avogadro's Number of atoms of the element as obtained from natural sources on Earth. For most elements, this atomic mass will be an average, weighted by natural isotope percentages, of the individual isotopes of the atom that naturally occur, but some elements have only one naturally occurring non radioactive isotope. The scale of atomic masses is now established by defining the mass of a carbon-12 isotope to be exactly 12. The atomic masses of other elements are defined by their mass ratios to a carbon-12 isotope.


What is the name of a carbon isotope that has a mass number of 12?

The isotope is named "carbon-12".
