How to do percent abundance
Web25 de ago. de 2024 · Given: exact mass and percent abundance. Asked for: atomic mass. Strategy: Convert the percent abundances to decimal form to obtain the mass fraction of each isotope. Multiply the exact mass of each isotope by its corresponding mass fraction (percent abundance ÷ 100) to obtain its weighted mass. WebSuppose you have a chlorine 35 and 37, each of their masses is 35 and 37, calculate their relative abundance if chlorine atomic mass is 35.45. Therefore, the relative abundance of chlorine 35 and 37 is 77.5% and 22.5 % respectively. Share. Tweet. Reddit. Pinterest. Email. Prev Article.
