Question

What is the average atomic mass of vibranium if this hypothetical superhero element is found to consist of 82.69% vibranium-306 (306.029 amu) and 17.31% vibranium-307 (307.030 amu)?

Answer 1

The average atomic mass of vibranium is 306.080 amu.

Step-by-step explanation:

To calculate the average atomic mass of vibranium, we need to multiply the mass of each isotope by its percent abundance and then sum the results. In this case, vibranium-306 has an abundance of 82.69% and a mass of 306.029 amu, while vibranium-307 has an abundance of 17.31% and a mass of 307.030 amu. Using these values, the calculation would be as follows:

Average atomic mass = (0.8269)(306.029 amu) + (0.1731)(307.030 amu) = 306.080 amu

Therefore, the average atomic mass of vibranium is 306.080 amu.
