Is the element cobalt rare?
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 %
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 abundance of argon gas?
It accounts ofr 0.934% by volume, of the earth's atmosphere.
How do you work out the percent abundance of two boron isotopes?
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.
Which is more stable cobalt 58 or cobalt 59?
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.
How common is cobalt?
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 %

How much argon is in the universe?
Its abundance is 0.02%
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.
What is the average atomic mass for cobalt?
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.
What is the natural percent abundance of the heavier isotope of gallium?
The natural percent abundance of the heavier isotope of gallium, gallium-71, is approximately 39.892%.
What is the percent abundance of argon gas?
It accounts ofr 0.934% by volume, of the earth's atmosphere.
Judging from the abundance of stars in the universe where does most of the hydrogen and helium come from?
From stars.
