Question

3. Calculate the average atomic mass of sulfur if 95.00% of all sulfur atoms have

a mass of 31.972 amu, 0.76% has a mass of 32.971u and 4.22% have a mass of
33.967u.

Answer 1

Average atomic mass = 32.057 u

Step-by-step explanation:

Average atomic mass = Σ(isotope × abundance)

Average atomic mass = (0.95 × 31.972) + (0.0076 × 32.971) + (0.0422 × 33.967)

Average atomic mass = 32.057 u
