80.0 g of iodine (v) oxide reacts with 28.0 g of carbon monoxide determine the mass of iodine

1 answer

I2O5+CO>> I2 + CO2
balance...

I2O5 + 5CO>>I2 + 5CO2

so the next is to see how many moles you have
28gCO/28= 1mol CO
80/334= .24 moles.

Since you need 5 mole CO per mole of I2O5, then I2O5 is limiting, and you have CO in excess.

so you will get .24mol I2, convert that to grams.
