1. Answer: Charge = -2.4×10^-9 Coulombs

   Explanation:

   The charge of one electron is e = -1.6×10^-19 C

   Then, the charge of 1.5 x 10^10 electrons is equal to 1.5 x 10^10 times the charge of one electron:

   Here i will use the relation (a^b)*(a^c) = a^(b + c)

   Charge = ( 1.5 x 10^10)*( -1.6×10^-19 C) = -2.4×10^(10 – 19) C  

   Charge = -2.4×10^-9 C
