Chapter 1, Problem 1
How many coulombs are represented by these amounts of electrons:
(a) (b) 1710482.6×181024.1×
(c) (d) 191046.2×2010628.1×
Chapter 1, Solution 1
(a) q = 6.482x1017 x [-1.602x10-19 C] = -0.10384 C
(b) q = 1. 24x1018 x [-1.602x10-19 C] = -0.19865 C
(c) q = 2.46x1019 x [-1.602x10-19 C] = -3.941 C
(d) q = 1.628x1020 x [-1.602x10-19 C] = -26.08 C
