This question involves the concepts of percent composition and atomic mass.
The percent composition of sulfur in H₂SO₄ is "A. 32.7 %".
First, we will find out the total mass of H₂SO₄ molecule:
Total Mass = 2(atomic mass of H) + (atomic mass of sulfur) + 4(atomic mass of O)
Total Mass = 2(1 g) + (32 g) + 4(16 g)
Total Mass = 98 g
Now, for percent composition of sulfur:
Percent Composition of Sulphur = [tex]\frac{atomic\ mass\ of\ sulphur}{total\ mass}(100\%)[/tex]
Percent Composition of Sulphur =[tex]\frac{32\ g}{98\ g}(100\%)[/tex]
Percent Composition of Sulphur = 32.7 %
