The mass percent, molality, molarity and mole fraction of toluene has to be calculated. Concept Introduction: Mass percentage of a compound can be defined by as calculated mass of the compound to the total mass of the compound whole multiplied by 100 . The mass percentage of a compound can be given by the equation, Mass percentage(%)= Calculated mass(g) Total mass(g) ×100

for this question. Write the molecular formula for a compound with the possible elements C, H, N and O that exhibits a molecular ion at M+ = 98.1106. Exact Masses of the Most Abundant Isotope of Selected Elements Isotope Natural abundance (%) Exact mass 1H 99.985 1.008 12C 98.90 12.000 14N 99.63 14.003 160 99.76 15.995 Molecular formula (In the order CHNO, with no subscripts)

PLEASE READ!!! I DONT WANT EXAMPLES, I DONT WANT WORDS OR PARAGRAPHS!!! PLEASE I UNDERSTAND THE BASICS BUT THIS IS AN EXCEPTION THAT EVEN THE INTERNET CANT HELP!!!! THIS IS THE THIRD TIME I'VE SENT THOSE QUESTIONS SO PLEASE DONT RESEND THE SAME STUFF, ITS NOT HELPING ME!!! I ALSO ALREADY TRIED TO DRAW THE MECHANISM MYSELF, SO IF ITS RIGHT PLEASE TELL ME OR TELL ME WHAT I HAVE TO CHANGE!!! First image: I have to SHOW (DRAWING) the mechanism (with arows and structures of molecules) NOT WORDS PLEASE! of the reaction at the bottom. Also I have to show by mecanism why the reaction wouldn't work if the alcohol was primary Second image: I have to show the mechanism (IMAGE) (with arrows and structures of the molecules) NOT WORDS PLEASE !! for the reaction on the left, where the alcohol A is added fast in one portion HOMEWORK, NOT EXAM!! ALL DETAILS ARE IN THE IMAGES PLEASE LOOK AT THE IMAGES, DONT LOOK AT THE AI GENERATED TEXT!!!
