Answer:

42.5g NH3 =2.5*6.022*10^23 NH3 atoms

= 1,505,500,000,000,000,000,000,000‬ atoms

Explanation:

molecular mass of NH3 = 17g

there fore number of moles present in 42.5g NH3 = 42.5g / 17 g

                                                                                    =2.5 moles

there fore number of atoms present in 42.5g NH3    

                                                                          =2.5*6.022*10^23

                                                                            NH3 atoms

                                     = 1,505,500,000,000,000,000,000,000‬    

                                        atoms
