Question

1.08gm How many molecules of quinine are there in Quinine?​

Answer 1

• Explanation:  Quinine molecular weight is 324

                                 Number of molecules = weight/ gram molecular weight

                                                                       = 108/324 × 6.023 × 10²³=1/3=0.3 moles× 6.023×10²³= 1.8069× 10²³molecules
