Its percent abundance is 0%.*
* Co60 has a relatively short half-life of 5.27 years, and so, is not found in nature at all. Therefore, its percent abundance is not relevant. It is produced artificially.
Cobalt is reasonably abundant. It is not rare. Abundance of cobalt in the earth crust: 25-35 mg/kg Abundance of cobalt in the sea water: 0,02 microgram/L Abundance of cobalt in the solar system: 2,3.10-3 atom mole fraction relative to silicon=1. Abundance of cobalt in the human body: 0,000 002 1 %
The percent abundance of boron is approximately 19.78% for ^10B and 80.22% for ^11B.
It accounts ofr 0.934% by volume, of the earth's atmosphere.
To determine the percent abundance of two boron isotopes, you would typically need experimental data from a mass spectrometry analysis. The percent abundance can be calculated by comparing the relative intensities of the peaks corresponding to the two isotopes in the mass spectrum. By dividing the intensity of each isotope by the sum of both isotopes' intensities and multiplying by 100, you can find the percent abundance of each isotope.
Cobalt-59 is more stable than cobalt-58. Cobalt-59 is the primary stable isotope of cobalt, with a natural abundance of around 100%, while cobalt-58 is a radioactive isotope with a half-life of about 70 days.

The percent abundance of boron is approximately 19.78% for ^10B and 80.22% for ^11B.
Its abundance is 0.02%
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
Take percent abundance times atomic mass for each isotope then add all up for average atomic mass.
The average atomic mass for cobalt is approximately 58.93 atomic mass units. It is calculated by taking into account the different isotopes of cobalt and their relative abundance in nature.
The natural percent abundance of the heavier isotope of gallium, gallium-71, is approximately 39.892%.
It accounts ofr 0.934% by volume, of the earth's atmosphere.
