when you cut an onion. It undergoes to water as shown by the following reaction: (CH3CO)2O+H2O2CH3CO2H H=60.86kJ Assuming you added a sample of acetic anhydride to excess water, and 3.55102kJ of Energy was released. Calculate the mass of acetic acid produced from this reaction. 4. Calculate the pH of a buffered solution made from mixing 20.0mL of 2.3mM salicyclic acid and 28.0mL of 4.6mM sodium salicyclate. The first pka of salicyclic acid was found to be 2.98 (reference: https://pubchem.ncbi.nlm.nih.gov/ ). The unit mM refers to millimolar concentration, and is used in industry frequently. You can use either a formula or an ICE Table to solve this problem. Show all work for full credit
