Given information: # atoms of Br in PBr3 = 3.68 * 10^25 Clarification: In PBr3, 1 mole of PBr3 accommodates 3 moles of Br Now, 1 mole of Br accommodates Avogadro quantity i.e. 6.023 * 10^23 atoms of Br Due to this fact, the # moles of Br corresponding to three.68*10^25 atoms can be: = 3.68 * 10^25 atoms * 1 mole Br/6.023*10^23 atoms = 61.099 moles of Br Since, 3 moles of Br is current in 1 mole of PBr3 then, 61.099 moles of Br would correspond to: 61.099 moles Br * 1 mole PBr3/3 moles Br = 20.366 moles of PBr3 Ans: 20.4 moles of PBr3
