You weighed out 0.020 g of your crude aspirin product in order to determine the amount of salicylic acid impurity. following the procedure outlined in the manual, you dissolved the solid and diluted the solution to a final volume of 10.0 ml. if the absorbance of your sample solution was 1.07, what was the percent salicylic acid in your product? (the pathlength for the cuvette was 1.0 cm.)

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.
