Question

Scientists predicted Adamantium would have an Atomic radius of 327 pm. Once the element was measured experimentally, they found that the atomic radius was really 312 pm. Calculate the percent error of their prediction

Answer 1

The actual atomic radius of Adamantium is 327pm. The experimentally estimated value of atomic radius of adamantium is 312pm. The percent error can be calculated as,

Percent error = (actual value-estimated value)/actual value *100

                       = 327-312/327*100

=Approx. 5 percent error in their prediction.
