a. Step 1: Determine the molar mass of
.- The molar mass of hydrogen (H) is approximately 1.01 g/mol.- The molar mass of sulfur (S) is approximately 32.07 g/mol.- The molar mass of oxygen (O) is approximately 16.00 g/mol.To calculate the molar mass of
, we need to add the molar masses of all the atoms in the compound:- Molar mass of
= (2 * 1.01 g/mol) + (1 * 32.07 g/mol) + (4 * 16.00 g/mol)- Molar mass of
= 2.02 g/mol + 32.07 g/mol + 64.00 g/mol- Molar mass of
= 98.09 g/molb. Step 2: Calculate the percent composition of sulfur in
.- To find the percent composition of sulfur, we need to divide the molar mass of sulfur by the molar mass of
and then multiply by 100.- Percent composition of sulfur = (Molar mass of sulfur / Molar mass of
) * 100- Percent composition of sulfur = (32.07 g/mol / 98.09 g/mol) * 100- Percent composition of sulfur ≈ 32.65%Solution: The percent composition of sulfur in
is approximately 32.65%.
