Question

Quizplus · Accepted Answer

The atomic mass of the element can be calculated by multiplying the abundance of each isotope by its mass and then summing these products. The calculation is as follows: (0.058 * 53.9396) + (0.918 * 55.9349) + (0.021 * 56.9354) + (0.003 * 57.9333) = 3.1283 + 51.3587 + 1.1950 + 0.1738 = 55.856 u, which rounds to 55.8 u.
