Two samples of potassium iodide are decomposed into their constituent elements. The first sample produced 13.0 g of potassium and 42.3 g of iodine. If the second sample produced 24.4 kg of potassium, how many kg of iodine were produced?

42.3/13=3.25 g of Iodine per gram of potassium
therefore 24.4x3.25=79.39 grams of iodine

if the amount of Iodine is x then
in the 1st
K / I = 13 / 42.3
in the 2nd
K / I = 24.4 / x
so
13/42.3 = 24.4 / x
x=24.4*42.3/13
x=79.393kg
