The dipole moment, mu, of a bond can be calculated from the equation mu = Q times r where Q is the magnitude of the partial changes and r is the bond length. Part B The dipole moment (mu) of HBr (a polar covalent molecule) is 0.831D (debye), and its percent ionic character is 12.3%. Estimate the bond length of the H-Br bond in picometers. Note that bullet 1 D = 3.34 times 10^-30 C-m and bullet in a bond with 100% ionic character, Q = 1.6 times 10^-29 C. Express your answer to two significant figures and include the appropriate units.
