Answer: 0.714 moles of will be produced from 237.1 g of potassium iodide
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
2 moles of produce = 1 mole of
Thus moles of will require=
of
Thus 0.714 moles of will be produced from 237.1 g of potassium iodide
