Uranium has three common isotopes. If the abundance of 234u is 0. 01%, the abundance of 235u is 0. 71%, and the abundance of 238u is 99. 28%, what is the average atomic mass of uranium?.



Answer :

The average atomic mass of uranium is 237.97 amu based on its three common isotopes.

Isotopes are the different forms of the same element. In considering the abundance of different isotopes of uranium for the calculation of its average atomic mass, the formula below is used.

Average atomic mass = summation of [(percent abundance /100)*atomic mass]

With the given three common isotopes of uranium, the calculated value of average atomic mass is shown below.

Average atomic mass= (0.01/100)(234 amu) + (0.71/100)(235 amu) + (99.28/100)(238 amu)

Average atomic mass=237.97 amu
