Problem 2E

Visualizing Concepts

These exercises are intended to probe your understanding of key concepts rather than your ability to utilize formulas and perform calculations.

Exercises with red numbers have answers in the back of the book.

The following diagram is a representation of 20 atoms of a fictitious element, which we will call nevadium (Nv). The red spheres are 293Nv, and the blue spheres are 295Nv.

(a) Assuming that this sample is a statistically representative sample of the element, calculate the percent abundance of each element.

(b) If the mass of 293Nv is 293.15 amu and that of 295Nv is 295.15 amu, what is the atomic weight of Nv? [Section]
