Calculate the mass fraction of sulfur in sulfuric acid.
| April 8, 2021 | education
The molar mass of sulfur is 32 grams / mol;
Determine the molar mass of sulfuric acid:
M H2SO4 = 1 x 2 + 32 + 16 x 4 = 98 grams / mol;
The mass fraction of sulfur in sulfuric acid will be equal to the ratio of the molar mass of sulfur to the molar mass of sulfuric acid.
K = M S / M H2SO4 = 32/98 = 0.3265 = 32.65%;
