(a) Explanation Given molecule is PCl 5 . This contains one phosphorus atom and give chlorine atoms. The atomic number of phosphorus is 15 . This means there are 15 protons present in a phosphorus atom. The number of protons and electrons will be the same and hence, there will be 15 electrons in the phosphorus atom. Mass number of phosphorus is 31 . Number of neutrons can be found by calculating the difference between mass number and atomic number. This can be done as shown below; Number of neutrons = Mass number − Atomic number =31 − 15 = 16 Therefore, in a phosphorus atom, there are 15 protons, 15 electrons, and 16 neutrons. Atomic number of chlorine is 17 . This means there are 17 protons present in a chlorine atom. The number of protons and electrons will be the same and hence, there will be 17 electrons in the phosphorus atom. Mass number of chlorine is 35 . Number of neutrons can be found by calculating the difference between mass number and atomic number. This can be done as shown below; Number of neutrons = Mass number − Atomic number =35 − 17 = 18 Therefore, in a chlorine atom, there are 17 protons, 17 electrons, and 18 neutrons. Total number of protons in one PCl 5 molecule: Total number of protons can be calculated by summing up the number of protons in the individual atoms (b) Interpretation Introduction Interpretation: Total mass of protons, of neutrons, and of electrons has to be calculated in one PCl 5 molecule.

What is the molecular weight of sugar, C6H12O6 in atomic mass units? And If you had one mole of sugar molecules, how much would it weigh?

Boron trifluoride is used as a catalyst in the synthesis of or-ganic compounds. When this compound is analyzed by massspectrometry several different 1+ ions form, including ions representing the whole molecule as well as molecular fragments formed by the loss of one,two, and three F atoms. Given that boron has two naturally occurring isotopes, ¹⁰B and ¹¹B, and fluorine has one, ¹⁹F, calculate the masses of all possible 1+ ions
