Answer:
Atomic mass of Sulfur is 32.07.
Explanation:
The four common isotopes of sulfur have masses of 31.972 amu (95.00 % abundance), 32.971 amu (0.76 %), 33.967 amu (4.22 %), and 35.967 amu (0.014 %).
The atomic mass of sulfur will be calculated using atomic mass of there isotopes and their respective decimal abundance.
Atomic mass of sulfur = ∑ isotope * abundance
= {(95/100) *31.972} + {(0.76/100) *32.971} + {(4.22/100) *33.967} + {(0.014/100) *35.967}
= (0.95*31.972) + (0.0076*33.971) + (0.0422*33.967) + (0.00014*35.967)
= 30.3734 + 0.2582 + 1.4334 + 0.00504
= 32.07 amu
Relative atomic mass of sulfur is 32.07
