Antimony reacts with sulfur according to this equation.
2Sb(s) + 3S(s) → Sb2S3(s)
What is the percentage yield for a reaction in which 1.40 g of Sb 2S3 (molar mass 339.7 g/mol) is obtained from 1.73 g antimony (molar mass 121.8 g/mol) reacting and a slight excess of sulfur (molar mass 32.07 g/mol)?
