Question

Silver has two isotopes: 107/47Ag, which has a mass of 106.905 amu and a percent abundance of 52.000%, and 109/47Ag, which has a mass of 108.905 amu and a percent abundance of 48.000%. What is the atomic mass of silver?

Answer 1

Answer:

Atomic mass = 107.865 amu

Explanation:

The atomic mass of an element is calculated as the sum of each isotope mass multiplied by its abundant.

For silver:

Atomic mass = 106.905 * 52.000% + 108.905 * 48.000%

Atomic mass = 107.865 amu
