How to calculate percent of abundance
Web27 aug. 2024 · How do you calculate percent abundance from relative atomic mass? As a percent, the equation would be: (x) + (100-x) = 100, where the 100 designates the total percent in nature. If you set the equation as a decimal, this means the abundance would be equal to 1. The equation would then become: x + (1 – x) = 1. WebHello!
