Percentage of Sulphur in Sulphuric acid is :

To determine the percentage of sulphur in sulphuric acid, we need to know the molecular formula of sulphuric acid, which is H2SO4.

Step 1: Calculate the molar mass of sulphuric acid. The molar mass of hydrogen (H) is 1 g/mol, the molar mass of sulphur (S) is 32 g/mol, and the molar mass of oxygen (O) is 16 g/mol. Since there are two hydrogen atoms, one sulphur atom, and four oxygen atoms in sulphuric acid, we can calculate the molar mass as follows: (2 * 1 g/mol) + (1 * 32 g/mol) + (4 * 16 g/mol) = 98 g/mol

Step 2: Calculate the molar mass of sulphur in sulphuric acid. Since the molar mass of sulphur is 32 g/mol, we can calculate the percentage of sulphur in sulphuric acid as follows: (32 g/mol / 98 g/mol) * 100% = 32.65%

Therefore, the percentage of sulphur in sulphuric acid is approximately 32.65%.
