PLEASE AND THANK YOU IN ADVANCE, will rate 5 stars and thumbs up plus recommend you! The spectrophotometer was used to measure the abosrbance of each of a series of [FeSal]+ solutions. A standard curve was constructed by plotting the absorbance vs. concentration (M). The slope and y-intercept were found to be 1493 M-1 and 0.005, respectively. An aspirin sample was prepared following the procedure given in the experiment. A 0.139 g sample of aspirin was hydrolyzed with 5 mL...

Need answer ASAP will give thumbs up
We dissolve 3.44 g of an unknown acid, HA, in enough water to produce 25.0 mL of solution. We titrate this solution with a 0.250 M solution of NaOH. It takes 18.3 mL of the NaOH solution to reach the equivalence point. The pH at the equivalence point is 12.00. (a) (3 points) What is the molar mass of HA? (b) (3 points) What is the pK, value of HA(aq)? (c) (3 points)...
