The distance between the atoms of H−Br is 1.41 Å. What is the distance in meters?

Express your answer in meters to three significant figures.

The dipole moment for a bond is a measure of the magnitude of polarity (how polar the bond is). Dipole moments can be used to calculate percent ionic character.

The dipole moment is symbolized by μ (Greek lowercase "mu") and is equal to the charge, Q, of the atoms (measured in Coulombs, C) times the distance, r, of separation between the atoms (measured in meters, m):

**μ = Q × r**

Therefore, the units of dipole moment are Coulomb-meters, C⋅m. Another unit of dipole moment is the debeye, D:

1 D = 3.34 × 10^{−30} C⋅m

The percent ionic character is calculated by dividing the charge, Q, by the charge on a single electron, 1.60×10^{−19} C⋅m.
