After creating a Beer's Law plot using standard solutions of Q, you determined the slope of Beer's Law to be 0.543 M-1. Your unknown solution of Q tested in Part B of the experiment had an absorbance of 0.144. Determine the concentration (in molarity) of the unknown solution Q from Part B. Do not use scientific notation or units in your response. If Carmen adds zeros after the decimal place, your answer will still be graded correctly.

Answer : The concentration (in molarity) of the unknown solution Q is, 0.265

Explanation :

Using Beer-Lambert's law :

where,

A = absorbance of solution

C = concentration of solution

l = path length

= molar absorptivity coefficient

From the Beer's Law plot between absorbance and concentration we concldue that the slope is equal to  and path length is 1 cm.

As we are given that:

Slope = 0.543 M⁻¹

and,

Slope =

Now we have to determine the concentration (in molarity) of the unknown solution Q.

Using Beer-Lambert's law :

Therefore, the concentration (in molarity) of the unknown solution Q is, 0.265

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
