To calculate the average atomic mass of neon, you need to consider the relative abundance of each isotope and its corresponding mass.
Let's denote the abundance of Ne-20 as x and the abundance of Ne-22 as y. Since there are only two isotopes of neon, the sum of their abundances will be equal to 1:
x + y = 1
Next, you can set up the equation using the atomic masses and abundances of each isotope:
(20 u * x) + (22 u * y) = average atomic mass
Now, you need to solve this system of equations to find the values of x and y. However, since you haven't provided the specific abundance values for Ne-20 and Ne-22, I am unable to calculate the exact average atomic mass of neon in this case.
If you provide the abundance values, I can assist you in calculating the average atomic mass of neon using the given information.
