Question

The average atomic mass of a sample of an element is 35 5u what are
the percentage of isotopes Ag17 35 in the
sample

Akanksha · Accepted Answer

Let the percentage of
17X35 = x

Percentage of
17X37 = 100 – x

Average atomic weight =
35 5u

Therefore 35 5 =

On solving the equation,
x = 75%

Therefore
17X35 = 75 %

And
17X37 = 100 – 75 = 25%

The average atomic mass of a sample of an element is 35.5u . what are the percentage of isotopes Ag17 35 in the sample.
