Assume that 8.5 L of iodine gas (I2) are produced at STP according to the following balanced equation:
2KI(aq) + Cl2(g) → 2KCl(aq) + I2(g)
How many moles of I2 are produced?
How many moles of Cl2 are used?
How many grams of Cl2 (g) are used?
moles of i2 8.5/22.4=0.379
moles cl2=moles of I2 so 0.379 moles
grams of cl2 0.379∗70.9=26.9g
