a wooden log weighs 25 kg .if entire log is made up of electron ,then find the no of electrons

Wt of one electron = 9.1 X 10-31 kg
Wt of   n electrons  =  25 kg
   n = 25/(9.1X 10-31)  = (25/9.1) X 1031   = 2.747 X 1031

Dear Friend,
An electron has a mass of about 9.10938215 × 10−31 kg.
Required number of electrons of 25 kg = 25 kg / 9.10938215 × 10−31 kg​ /electron
... 2.2773320375 x 1031
