Dear Student,

$(i) n o o f e l e c t r o n l o s t b y r o d = \frac{19.2 \times 10^{- 19}}{1.6 \times 10^{- 19}} = 12 e l e c t r o n h a s b e e n t r a n s f e r e d . (i i) c h a r g e a c q u i r e d b y s i l k = - 19.2 \times 10^{- 19} C (i i i) y e s \sin c e m a s s o f t h e e l e c t r o n i s c o n s i d e r a b l e t h e m a s s h a s b e e n t r a n s f e r e d .
