A)0.25, 99.75 B)99.75, 0.25 C)49, 51 D)1.0, 99 E)99, 1.0

Question

Quizplus · Accepted Answer

The atomic weight of vanadium is closer to the atomic mass of ⁵¹V, indicating that ⁵¹V is much more abundant. Calculating the weighted average using the given atomic masses and atomic weight confirms that ⁵⁰V has an abundance of approximately 0.25% and ⁵¹V has an abundance of approximately 99.75%.
