Question

If the resultant dipole moment of water is
1.85D, then what is its value in terms of C-m?

Answer 1

Answer:

51

Explanation:

1 debye=3.336x10^-30

Answer 2

Concept:

Dipole Moment: Consider a system containing two opposite charges separated by some distance. The product of one of the charges and the distance between the charges is called dipole moment (p).

p = qr

where q = charge

r = distance between the charges.

Dipole moment is measured in debye (D) and C m.

Given:

Dipole moment of water, p = 1.85 D

Find:

The value of dipole moment in C-m (Coulomb meter).

Answer:

The relation between debye (D) and coulomb - meter (C-m) is,

1 D = 3.33 × 10⁻³⁰ C-m

∴ 1.85 D = 1.85 × 3.33 × 10⁻³⁰ C-m

             = 6.1605 × 10⁻³⁰ C-m

Hence, the resultant dipole moment of water in terms of C-m is

6.1605 × 10⁻³⁰ C-m.
