Sulfur and fluorine form several different compounds including sulfur hexafluoride and sulfur tetrafluoride. Decomposition of a sample of sulfur hexafluoride produces 4.45 g of fluorine and 1.25 g of sulfur, while decomposition of a sample of sulfur tetrafluoride produces 4.43 g of fluorine and 1.87 g of sulfur. Calculate the mass of fluorine per gram of sulfur for each sample and show that these results are consistent with the law of multiple proportions.
Solution 38E (a) Mass spectrum is the graph of intensity vs mass-to-charge ratio for representing a chemical analysis.Hence, the mass spectrum of a sample is a pattern representing the distribution of ions by mass-to-charge ratio in a sample. The purpose of magnet in the mass spectrometer is to deflect the ions which passed through the slits into a curved path. For ions with the same charge, the extent of deflection depends on mass i.e the more massive the ion, the less the deflection. Hence, ions are separated according to their masses. (b) In this figure, we see the signal intensities of the beams reaching the detector of the mass spectrometer. These signals are the fractional abundances of the isotopes Cl and Cl. The mass spectrum of Cl does not show a peak at 35.5 amu because it's the average atomic mass of Cl. It is not the atomic mass of naturally occurring isotope. (c) If in the Mass spectrum of phosphorus atom (P), there is only a single peak that means relative abundance of 31P is minimum and only one single isotope occurs.
