What is the mass of carbon-13 in amu?
Carbon-13 has a mass of 13.003355 amu at 1.11% abundance. Once you do the math you come up with the average atomic mass for natural carbon to be 12.01 amu, which is what is listed on ALL periodic tables. Fun fact though: there isn’t a single atom of carbon with the mass of 12.01.
How do you find the atomic mass of carbon-13?
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.
Where is carbon 13 found?
C and 13C are stable, occurring in a natural proportion of approximately 93:1. C is produced by thermal neutrons from cosmic radiation in the upper atmosphere, and is transported down to earth to be absorbed by living biological material.
What is carbon 13 called?
Isotopes of Carbon By far the most common isotope of carbon is carbon-12 (12C), which contains six neutrons in addition to its six protons. The next heaviest carbon isotope, carbon-13 (13C), has seven neutrons. Both 12C and 13C are called stable isotopes since they do not decay into other forms or elements over time.
What is the symbol for carbon 13?

What do we use carbon 13 for?
C-13 is used for instance in organic chemistry research, studies into molecular structures, metabolism, food labeling, air pollution and climate change. C-13 is also used in breath tests to determine the presence of the helicobacter pylori bacteria which causes stomach ulcer.
How do you calculate the atomic mass of carbon?
The atomic mass of carbon would be 12.01 grams per mole of carbon atoms. To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons.
What is the approximate size of a carbon atom?
The diameter of a carbon atom is 0.000 000 000 154 m. This number expressed in scientific notation is 1.54 x 10^-10 m.
What can the atomic mass tell you?
Atomic mass units tell the mass of one mole of a given element or molecule in grams. This is a very useful property when it comes to practical calculations, as it allows easy conversion between the mass and moles of a given quantity of atoms or molecules of the same type.
How many protons neutrons and electrons are in Carbon 13?
Carbon-12 is composed of 6 protons, 6 neutrons, and 6 electrons. Carbon-13 is a natural, stable isotope of carbon with a nucleus containing six protons and seven neutrons. As one of the environmental isotopes, it makes up about 1.1% of all natural carbon on Earth.
