Answer :
The formula for mustard gas used in chemical warfare is C₄H₈SCl₂ . the percentage of carbon in the compound is 30.1 %
given that :
The chemical formula for mustard gas = C₄H₈SCl₂
The mass of the mustard gas , C₄H₈SCl₂ = 159.09 g/mol
The formula to calculate percentage of the element in the compound is expressed as follows :
The percentage of carbon = (mass of carbon / mass of compound ) × 100 %
The percentage of carbon = ( 4 × 12.01 / 159.09) × 100 %
The percentage of carbon = (48.04 / 159.09 ) × 100 %
The percentage of carbon = 0.301 × 100 %
The percentage of carbon = 30.1 %
Thus, The percentage of carbon is 30.1 %
