How do you calculate the atomic weight of a chemical element that has two or more isotopes?
To calculate the atomic weight of an element with multiple isotopes, you multiply the mass of each isotope by its relative abundance (as a decimal), then sum the products. The result is the atomic weight of the element, which is a weighted average of the masses of its isotopes based on their abundance in nature.
Why is each isotope's mass multiplied by the isotope's percent abundance?
Each isotope's mass is multiplied by its percent abundance to account for the contribution of each isotope to the overall average atomic mass of an element. This calculation ensures that the final average atomic mass reflects the weighted average of the masses of all isotopes based on their abundance in nature.

What is the percent composition in lithium and bromine?
The percent composition of lithium in lithium bromide (LiBr) is approximately 7.7%. The percent composition of bromine in lithium bromide is approximately 92.3%.
What is the percent 59.7 lithium mass of 100 g of the compound?
The percent mass of lithium in a compound with 100 g is calculated by dividing the mass of lithium by the total mass and multiplying by 100. So, if the compound contains 59.7 g of lithium, the percent mass of lithium would be (59.7 g / 100 g) * 100 = 59.7%.
What is the percent composition of lithium in LiBr?
The percent composition of lithium in LiBr is approximately 7.0%. This is calculated by dividing the molar mass of lithium by the molar mass of LiBr and then multiplying by 100.
What percent of the sun is made of lithium?

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 composition of Li in LiOH?
The molar mass of LiOH is 23.95 g/mol for Li, 15.999 g/mol for O, and 1.008 g/mol for H. The molar mass of LiOH is 23.95 + 15.999 + 1.008 = 40.957 g/mol. Therefore, the percent composition of Li in LiOH is (23.95/40.957) x 100 = 58.44%.
What is the percent of composition for LiBr?
LiBr contain 8,139 % lithium and 91,860 % bromine.
