Element X has 5 isotopes. Out of every 220 X atoms, 11 atoms have a mass of 176 u, 41.8 atoms
3.1
have a mass of 177 u, 59.4 atoms have a mass of 178 u, and the other two have a mass of 179 u
и,
and 180 u. The relative atomic mass of X is 178.49 u.
a. Calculate the percentage abundance of 179X and180x.
b.
Write the name (not the symbol) of the element in question.
Write the nuclide symbol of the most abundant isotope of this
element.
с.
Expert Solution

Step 1
Let the number of atoms be x of 179u Isotope, then number of atoms of 180u isotope will be 220 -(11+ 41.8+59.4+x) = (107.8 - x).
