There are only two isotopes of an element with 69 and 71 neutrons. The relative atomic mass of the Element is 69.72. What is the % abundance of each, i got the equation
(%no 1 * 69) + ((100 - %no 1 ) * 71)/100 where do i go from here?
(%no 1 * 69) + ((100 - %no 1 ) * 71)/100 where do i go from here?
