Solution: What is the percent yield of the reaction below if 55.3 g of solid iodine (molar mass = 253.8 g/mol) react with an excess of hydrogen gas to produce 43.1 g (the actual yield) of hydrogen iodide gas (m

What is the percent yield of the reaction below if 55.3 g of solid iodine (molar mass = 253.8 g/mol) react with an excess of hydrogen gas to produce 43.1 g (the actual yield) of hydrogen iodide gas (molar mass = 127.91 g/mol)? 

H₂ (g) + I₂ (s) → 2HI (g) 

(i) 21.8% 

(ii) 33.7% 

(iii) 77.3% 

(iv) 87.1%
