The natural abundance of Ag-109 can be calculated by subtracting the natural abundance of Ag-107 (51.84%) from 100%, since these two isotopes make up 100% of all naturally occurring silver isotopes. Thus, the natural abundance of Ag-109 is 48.16%.
The percent abundance of boron is approximately 19.78% for ^10B and 80.22% for ^11B.
The natural abundance of Cl-35 is approximately 75.77%.
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.
The natural percent abundance of the heavier isotope of gallium, gallium-71, is approximately 39.892%.
The natural abundance of Ag-109 can be calculated by subtracting the natural abundance of Ag-107 (51.84%) from 100%, since these two isotopes make up 100% of all naturally occurring silver isotopes. Thus, the natural abundance of Ag-109 is 48.16%.
The natural abundance of 63Cu is about 69.17%.
the natural abundance of chlorine 3 is 24.23%
The percent abundance of boron is approximately 19.78% for ^10B and 80.22% for ^11B.
The natural abundance of Br-81 is approximately 49.31%.
50.69% natural abundance
The natural abundance of Cl-35 is approximately 75.77%.
The abundance of N-15 is approximately 0.37% of natural nitrogen.
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.
It accounts ofr 0.934% by volume, of the earth's atmosphere.
