(a)
Interpretation: The ratio of lead contained in the two compounds for every 1 g of iodine is to be determined.
Concept Introduction: The law of multiple proportions states that, when two elements combine to form more than one compound, then the masses of the second element which combine with a fixed mass of the first element will always bear a simple whole number ratio.
(a)
Answer to Problem 89A
The ratio of lead present in two compounds for every 1 g of iodine is 2:1.
Explanation of Solution
The amount of lead present in compound I for every 1 g of iodine is 0.816 g. and that of lead present in compound II is 0.408 g. so the ratio between these two is 1.7:1
