Video transcript

Hello everyone today. We are being given the following problem and asking to solve for it, cesium iodide has a cesium to iodine mass ratio of 1.4721. When a sample of the cesium iodide is completely decomposed, 27.88 g of cesium is produced. What mass of iodine in grams is produced. So first we want to make note of our cesium iodine ratio And we're gonna use this ratio to calculate for the mass of iodine in this sample. So our massive iodine is 27. g of cesium. Everybody multiplied by that ratio that we have. So for every one g of iodine that we have, we have 1.47 g of cesium. And this is per that ratio given to us in the question stem Our units are going to cancel out our g of season, cancel out. And we will be left with 26.63 g of iodine as our final answer. I hope this helped. And until next time

Sulfur and oxygen form both sulfur dioxide and sulfur trioxide. When samples of these are decomposed, the sulfur dioxide produces 3.49 g oxygen and 3.50 g sulfur, while the sulfur trioxide produces 6.75 g oxygen and 4.50 g sulfur. Calculate the mass of oxygen per gram of sulfur for each sample and show that these results are consistent with the law of multiple proportions.
