In this question, it says that naturally occurring chlorine consists of chloroing 35 with atomic mass of 34 .96885 amu, and chloroity 7 with atomic mass of 36 590 amu, with an average mass of 35 .453 amu.
00:22
What is the chlorine in terms of those, these two icetives? that is the present composition of chlorine.
00:28
So let's solve it.
00:34
So our average atomic mass is given us 35 .453 amu.
00:45
Let our abundance of chlorine 35 been equal to x and then let our percentage abundance of chloroint 37 been equal to y.
01:07
Well, y is equal to 1 minus x.
01:11
So we have our average atomic mass being equal to 35 .453 been equal to our atomic mass of gram 35 which is 34 .96 -885 into brackets x plus our atomic mass of gram 37 which is 36 .96 590 into bracket 1 minus s which is y so we have 35 .453 been equal to 34 .96 885x plus 36 .865 x plus 36 .96590 minus 36.
02:28
960x so we have 36 .960 x been equal to 36 .36 .36 minus 34 .96 885 x been equal to 36 .36 .36 34 .453.
03:14
So you have an answer of 1 .99705 x been equal to 1 .529...
