Answer:
Step-by-step explanation:
There are 6 32S atoms and 2 36S atoms
Their respective contributions to the average aomic mass is (6*32)=192, and (2*36)=72. Added together, this makes 264 total. Divide by the total number of atoms, 8. (264/8) = 33.00
The weighted atomic mass of these S atoms is 33.00 amu (atomic mass units)
