The concentration of a dilute aspirin solution is 0.000550 M . Standard solutions of this compound were used to prepare a Beer's law plot which gives a slope of 1550.2 M−1 . What is the expected absorbance value for the aspirin solution?

the right answer is c i just did the question.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
