The percent abundance of Carbon-13 (¹³C) in naturally occurring carbon is approximately 1.1%. This isotope accounts for a small fraction of carbon found in nature, with the majority being Carbon-12 (¹²C), which makes up about 98.9% of carbon. The presence of Carbon-13 plays a significant role in various scientific applications, including radiocarbon dating and studying metabolic processes.

How does the atomic mass of carbon show that it is an isotopes?
If your asking "how does the mass show there are isotopes", then the answer is this: Isotopes are found by using a mass spectrometer, and the abundance (percent amount) of each isotope is determined. Using this percent of abundance, the AVERAGE mass is reported on the periodic table. For example, if carbon 12 had mass of 12 and carbon 13 had mass of 13, but the percent abundance of 12 was 99% and the abundance of 13 was 1%, then the atomac mass would be 12*.99+13*.01=12.01 You can tell it has isotopes by seeing that the mass is a decimal and not a whole number. It is harder to tell with carbon, because it's only off by .01, but looking at chlorine it is more clear. Most isotope weights are very close to being whole numbers, like Cl35 mass is 34.98 and Cl37 is 36.97. But looking at Cl atomic weight, it is 35.45; the .45 tells you it is a average because the value lies between the whole numbers as a decimal. Cl is 35.45, which is an average of 35 and 37 that's 76% and 24% abundance respectively.
How many C-13 atoms are present on average in a 13000-atom sample of carbon?
Carbon-13 make up 1.1% of carbon atoms. .011 x 19000 carbon atoms = 209 carbon-13 atoms present.

What is the percent abundance for boron?
The percent abundance of boron is approximately 19.78% for ^10B and 80.22% for ^11B.
What is the percent yield for carbon disulfide if the reaction of 40.0g of carbon produces 33.0g of carbon disulfide?
This yield is very low - 13 %.
What percent of Mars is carbon dioxide?
The atmosphere of Mars is almost entirely CO2.
What is is the result when you total the individual relative abundance?
the result is 1.00, because relative abundance is just the percent abundance in decimal form. The percent abundance sum is 100%, therefore the answer is 1.00 because the decimal of 100% is 1.00
What is percent abundance?
Take percent abundance times atomic mass for each isotope then add all up for average atomic mass.
Where can carbon be found?
Carbon is found in abundance in the sun, stars, comets and atmospheres
