Answer 2

$\huge\mathfrak\red{★answer★} \: \: \: ✍$

copper has two naturally occurring isotopes, copper-63 and copper-65. This means that their respective decimal abundance must add up to give 1.If you take x to be the decimal abundance of copper-63, you can say that the decimal abundance of copper 65 will be equal to

1-x. Therefore, Copper-63x:62.9296u+ copper

65(1-x).64.9278u=63.546uSolve this equation for x to

get62.9296.x-64.9278.x=63.546-64.9 2781.9982.x=1.3818+x=1.38181.998

2=0.69152This means that the percent abundances of the two isotopes will

be. 69.152%-63Cu. 30.848%-65Cu
