Questions & Step-by-Step Solutions
Calculate the dipole moment of a molecule with a charge of 1.6 x 10^-19 C and a bond length of 1.5 Å.
Step 1: Identify the charge (q) of the molecule, which is given as 1.6 x 10^-19 C.
Step 2: Identify the bond length (d) of the molecule, which is given as 1.5 Å. Convert this to meters: 1.5 Å = 1.5 x 10^-10 m.
Step 3: Use the formula for dipole moment (p), which is p = charge (q) × distance (d).
Step 4: Substitute the values into the formula: p = (1.6 x 10^-19 C) × (1.5 x 10^-10 m).
Step 5: Calculate the result: p = 2.4 x 10^-29 C·m.
Dipole Moment – The dipole moment is a measure of the separation of positive and negative charges in a system, calculated as the product of charge and distance.
Unit Conversion – Understanding the need to convert units (e.g., from angstroms to meters) when performing calculations.
