Determine the mass of iodine and fluorine in Compound 3 from the data provided. For Compound 3, the mass of iodine is 9.41 grams and the mass of fluorine is 9.86 grams.
Set up the ratio of the mass of fluorine to the mass of iodine for Compound 3. This ratio can be calculated using the formula: \( \text{Ratio} = \frac{\text{Mass of Fluorine}}{\text{Mass of Iodine}} \).
Substitute the values into the formula: \( \text{Ratio} = \frac{9.86 \, \text{g}}{9.41 \, \text{g}} \).
Calculate the ratio by dividing the mass of fluorine by the mass of iodine. This will give you the mass of fluorine per gram of iodine in Compound 3.
The result from the calculation will provide the mass of fluorine per gram of iodine, which is a measure of how much fluorine is present relative to iodine in the compound.

Mass Ratio

The mass ratio is a comparison of the mass of one substance to the mass of another substance. In this context, it refers to the mass of fluorine relative to the mass of iodine in a compound. This ratio is crucial for understanding the composition of the compound and can be calculated by dividing the mass of fluorine by the mass of iodine.
