Question

What mass of iodine is produced when 14.2 grams of chlorine reacts with potassium iodine?

Answer 1

50.8g of iodine is produced.

Step-by-step explanation:

You have to do stoichiometry. To get grams of iodine produced.

1. Start with grams of chlorine that you're given
2. Convert these to moles (using molar mass)
3. Convert moles of Cl2 into moles of I2
4. Convert moles of I2 into grams of I2 (using molar mass)

(Remember to multiply across the top and divide by the bottom)

`(14.2g Cl2)/(1) * (1 mol Cl2)/(70.9g) * (1 mol I2)/(1mol I2) * (253.8g)/(1 mol I2)`
