Explanation:
I'm not sure if this is what you are looking for but i will attempt to answer.
Isotopes are variations of the same atom. They have the same number of protons but have a different number of neutrons. As a result of this, the atomic number remains the same but the mass number changes.
A calculation you could perform in relation to isotopes would be calculating the relative atomic mass. The relative atomic mass is the weighted average of masses of isotopes.
Relative atomic mass (RAM)= the addition of

For example, the element Indium has a relative isotopic mass of 112.90406, 4.29% of the time. It has a relative isotopic mass of 114.903878, 95.71% of the time.
From this
RAM=

Answer:
This type of meat is substance. If you were talking about meters then it would be a system of measurement.
If you'd like the full working, here it is:
I calculated this by using the formula triangle.
Mass
Number Formula
Of moles Mass
To calculate the number if moles in a substance, you need to divide the Mass by the Formula mass. You get the formula mass by adding the atomic masses of the elements in the compound together. In this situation, H2O, it would be two hydrogen molecules plus one oxygen molecule which is 2 + 16. This is because the atomic mass of Hydrogen is 1 and the atomic mass of Oxygen is 16.
Now that we have the Formula mass we can go ahead and do the calculation since we already have the Mass. You do as follows:
Mass divided by Formula mass which is in this case - 25 divided by 18
By doing this calculation you will get the answer which is 1.38 moles which can be rounded to 1.4
Hope this helps :)
The average atomic mass of your mixture is 1.03 u
.
The average atomic mass of H is the weighted average of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its % abundance).
Thus,
0.99 × 1.01 u = 0.998 u
0.002 × 2.01 u = 0.004 u
0.008 × 3.02 u = <u>0.024 u</u>
TOTAL = 1.03 u
