Hi!

I am a high school chemistry student and I have a lab due tomorrow, and I’m stuck


so basically, I know that when acetylsalicylic acid (aspirin) reacts with water it produces salicylic acid and acetic acid via hydrolysis.


Now I’m confused about the relationship so if I dissolve 0.04g of acetylsalicylic acid with 20mL of water, and then on my next trial I dissolve 0.03 grams of acetylsalicylic acid with 20 mL of water and then finally I dissolve 0.02 g of acetylsalicylic acid with 20mL of water, I’m decreasing the mass of of acetylsalicylic acid each time, so since I know salicylic acid is produced when acetylsalicylic acid reacts with water, what will happen to the concentration of salicylic acid produced if the mass of acetylsalicylic acid (the reactant) is decreased each time with a fixed volume of water. Would the concentration of salicylic acid decrease? If so, what is the chemistry behind this, and the relationship between the reactants and products.


Thank You in Advance !

34g of ammonia, NH3, is put into a container at STP. What is the volume of the container?

If you reacted 112 mg of maleic anhydride and 0.11mL of (E,E)-2,4-hexadien-1-ol what is your theoretical yield and what is the limiting reagent.


I understand how to find the limiting reagent. The calculations are shown below. I need help with the theoretical yield please!!!

The limiting reagent is (E,E)-2,4-hexadien-1-ol.


Maleic anhydride:


112 mg x (10-3g/ 1 mg) = 0.112 g


0.112 g x (1 mol/98.06g)= 0.00114 mol


(E,E)- 2,4-hexadien-1-ol :


0.11 mL x (0.871g/ 1mL) =0.09581 g


0.09581 g x (1 mol/ 98.14g) = 0.000976 mol [limiting reagent]
