We have that the  the isotopic mass of 13M  is mathematically given as

  • x=12.867amu

From the question we are told

  • A generic element, M, has two isotopes, 11M and 13M, and an average atomic mass of 11.66 amu.
  • The natural abundances of the two isotopes are 65% 11M and 35% 13M.
  • The isotopic mass of 11M is 11.01 amu.
  • What is the isotopic mass of 13M

lsotopic mass

Generally the equation for the  average atomic mass is mathematically given as

Average atomic=abundance * 11M+abundance * 13M

Therefore

[tex]11.66=(0.65*11.01)+0.35*x\\\\Hence\\\\\x=\frac{4.5035}{0.35}[/tex]

  • x=12.867amu
