Calculate the Ratio of Lead to Iodine in Two Compounds

Explanation:

To calculate the ratio of lead to iodine in each compound, we assume a base of 100 grams for each compound.

First compound:

We are given that lead constitutes 44.94% by mass in the first compound. Therefore, the mass of lead is 44.94 grams and the mass of iodine would be 100 - 44.94 = 55.06 grams. To find the ratio of lead to iodine, we divide the mass of lead by the mass of iodine: 44.94 grams lead / 55.06 grams iodine = 0.8162 grams of lead per gram of iodine.

Second compound:

In the second compound, lead constitutes 62.02% by mass. This means the mass of lead is 62.02 grams and the mass of iodine is 100 - 62.02 = 37.98 grams. Dividing the mass of lead by the mass of iodine gives us the ratio of lead to iodine in the second compound: 62.02 grams lead / 37.98 grams iodine = 1.633 grams of lead per gram of iodine.

Therefore, the ratio of lead to iodine is 0.8162 grams per gram in the first compound and 1.633 grams per gram in the second compound.
