The metal component of the given compound, CrCl3, is chromium. The number of moles per 1 g of chromium is calculated through the equation below,
n = (1 g Cr)(1 mol Cr/51.996 g Cr)
n = 0.0192 mol Cr(3 electrons/1 mol Cr)
n = 0.0577 e-
Determine the number in charge by multiplying with Faraday's constant,
C = (0.0577 mol Cr)((1 F/1 mol e-)(96485 C/ 1F)
C = 5,566.87 C
Then, calculate time by dividing the charge with the current,
t = 5566.87 C/1.5 A
t = 3711.25 minutes
t = 61.84 hours

Let us assume that this molecule is 100 percent ionic. In that case, the charges are distinguished by a bond length.
h = Q × r
= (160 × 10⁻¹⁹ c) (127 × 10⁻¹² m) (10 / 3.336 × 10⁻³⁰ cm)
= 6.09 D.
The actual dipole moment is = 1.08 D
Therefore, the percent ionic character is,
= 1.08 D / 6.09 D × 100
= 17.7 %.
The atomic mass of an element provides A. the number of protons and neutrons in an atom.
