Uranium is used in nuclear reactors and is a rare element on earth. 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

Average atomic mass of uranium= 237.98 amu.

Explanation:

Given data:

Abundance of U²³⁴ = 0.01%

Abundance of U²³⁵ = 0.17%

Abundance of U²³⁸ = 99.28%

Average atomic mass = ?

Solution:

Average atomic mass of uranium = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) +(abundance of 3rd isotope × its atomic mass) / 100

Average atomic mass of uranium= (234×0.01)+(235×0.71)+(238×99.28)/100

Average atomic mass of uranium=  2.34 + 166.85 + 23628.64 / 100

Average atomic mass of uranium= 23797.83 / 100

Average atomic mass of uranium= 237.98 amu.
