Question

on chemical scale, the relative mass of the isotopic mixture of x atoms (x^20,x^21,x^22) is approximately equal to:(x^20 has 99 percent abundance)

Answer 1

As we know that the mass of any element is somewhat more than the mass of its isotope which has highest concentration. So in this case X^20 has 99% of its abundance. Hence weight of X element shoulď be a little more greater than 20 as other isotopes has its abundance of 1%. Therefore after checking the options, we would find that its answer is 20.002

Answer 2

Answer:

Explanation:

Isotropic definition:

An object's qualities are said to be isotropic if they are unaffected by orientation, whereas anisotropic means they are. In elementary crystallography, these two phrases are employed to describe the properties of the substance.

If 99 percent equals 20, then the sum must be close to 20.

Note: Before realizing you had writer's cramp from all of your inquiries, I stated at the top and worked down. Although this is not the place to dump your assignments, I have assisted with each for today. In the future, you should present your work, illustrate how you would respond to the inquiries, and—perhaps most crucially—explain precisely what you don't understand about the issue or subject. I can better answer your issues if you are more specific about the part that is bothering you.
