Using your data, calculate the moles and mass of acetylsalicylic acid in each tablet (molar mass = 180.16 g/mol).
Molar mass of Acetyl salicylic acid given as 180.16g/mol
That means 180.16 gm of acetylsalicylic acid is = 1 mol
1 gm of acetylsalicylic acid is = 1/180.16 mol
Trial 1 mass 0.161 gm of acetylsalicylic acid is = (1/180.16) 0.161 mol = 8.94 10-4 mol
For trial 2 mass 0.282 gm of acetylsalicylic acid is = (1/180.16) 0.282 mol = 1.5710-3 mol
Using your data, calculate the moles and mass of acetylsalicylic acid in each tablet (molar mass ...
Can someone please help me Determine the concentration of Sodium hydroxide using the data from the standardization experiment? For analysis #3, the pH at half way to equivalence is not evaluated by this program, since it did noheg your titration data. Because it cannot evaluate it, it will assume it is correct for all subsequent calc you are using the correct value here.

II. Digestion of Acetylsalicylic acid(standard and tablet) with NaOH . Digestion of Acetylsalicylic Acid Standard to Prepare Stock Solution: Obtain ca. 0.1 g dried acetylsalicylic acid (MM = 180.16 g/mol), accurately weighed, and quantitatively transfer to a 125-ml Erlenmeyer flask. Add 5 ml 1.0 M NaOH and heat mixture to boiling on a hot plate. This will hydrolyze the acetylsalicylic acid to sodium salicylate. If necessary, rinse down the walls of the Erlenmeyer with DI water to ensure complete hydrolysis...

Aspirin is acetylsalicylic acid (ASA) ( C9H8O4). It reacts with NaOH ( a base) to produce salt (sodium acetylate) and water. Both Aspirin and NaOH react in 1:1 molar ratio, as C9H8O4 + NaOH → NaC9H7O4 + H2O So, moles of NaOH = moles of ASA Or, mmol of of NaOH = mmole of ASA ; mmol is milli mol and mmole of NaOH = Molarity of NaOH * Volume of naOH used (in ml) = (0.1177 M) *...
