Submit My Answers Give Up Incorrect; Try Again; 3 attempts remainingExplanation / Answer
A)
q = 1.602*10^-19 C
d = 85 pm = 85*10^-12 m = 8.5*10^-11 m
use:
dipole moment = q*d
= (1.602*10^-19 C)*(8.5*10^-11 m)
= 1.4*10^-29 C.m
Answer: 1.4*10^-29 C.m
B)
q = 1.602*10^-19 C
d = 170 pm = 170*10^-12 m = 1.70*10^-10 m
use:
dipole moment = q*d
= (1.602*10^-19 C)*(1.70*10^-10 m)
= 2.7*10^-29 C.m
Answer: 2.7*10^-29 C.m
