In an Honors organic chemistry lab, a student devised an experiment in which she would treat benzoic acid with t-butanol in an a
cid-catalyzed esterification reaction using concentrated sulfuric acid. Regretfully, the synthetic yield of the expected ester was exceedingly low. Please explain this outcome in terms of the chemistry that actually occurred in the reaction flask. [This attempted esterification reaction would have been better suited to dicyclohexylcarbodiimide (DCC/pyridine) esterification conditions.]

Answer:
37.3g
Explanation:
Formula of the compound:
FeCl₃
Number of chloride ions = 4.13 x 10²³ ions
First find the number of moles in this ions;
6.02 x 10²³ ions are contained in 1 mole of a substance
4.13 x 10²³ ions contains = 0.69mole chloride ions
Now;
3 mole of chloride ions are contained in 1 mole of FeCl₃
0.69 mole of chloride ions will contain = 0.23mole of FeCl₃
To find the mass;
Mass of FeCl₃ = number of moles x molar mass
molar mass of FeCl₃ = 55.8 + 3(35.5) = 162.3g/mol
Mass of FeCl₃ = 0.23 x 162.3 = 37.3g
