Answer this question:-

Potassium iodide is used as dietary supplement to prevent goiter, an iodide deficiency disease. It is prepared b the reaction of hydrogen iodide and potassium hydrogen carbonate.


HI + KHCO3 = KI + H2O + CO2


How many grams of KI can be made by mixing 481 g HI?

Answer 1

moles of HI = 481/128 = 3.76
now according to equation
1 mole HI form 1 mole of KI
so 3.76 moles of HI will form 3.76 moles of KI
hence, moles = weight / molar mass
3.76 = w / 166
w = 3.76 x 166 = 623.79 gram.
