It's a trick question because all of them contain both iconic and covalent bonds.
Hope it helps!! :) have fun
Answer:
2.448 * 10^-5M
Explanation:
To calculate the concentration of the solution, we apply the Beer Lambert law equation.
That is A = £LC
Where £ represents the molar extinction coefficient.
We identify the values as follows:
A = absorbance = 0.735
L = cell length = 1.30
£ = 23100
c = concentration = ?
Rearranging the equation, c = A/£L
c = 0.735/(23,100 * 1.3)
c = 2.448 * 10^-5 M
The answer is B. two chlorine atoms.
The chemical formula of the compound is BaCl2~
