Question

Calculate percentage of sulphur in sulphuric acid

Answer 1

■■■■

in sulphuric acid, there is 32.69% of sulphur present

■■■■

molar mass of hydrogen = 1.008 g/mol

molar mass of sulphur = 32.066 g/mol

molar mass of oxygen = 15.999 g/mol

■■■■■

Molar mass of H2SO4 = (1.008 x 2) + (32.066) + (15.999 x 4) = 98.078 g/mol

■■■■■

percentage of sulphur (32.066/98.078)×100 = 32.69%
