Units for required dose and stock dose must be the same. Certain adults who are not in pain are recommended by doctors to take a smaller 75 mg dose of aspirin each day. Then calculate the scale factor for each solid sample and multiply it by the Vc mass (in mg) from the relevant titration to obtain the mass result for that trial. Chemistry 104: Analysis of Commercial Antacid Tablets. The reaction, using molecular formulas is C7H6O3 + C4H6O3 --> C9H8O4 + C2H4O2. 0 g O Find: empirical formula Step 2 Convert each of the masses in step 1 to moles by using the appropriate molar mass for each element as a conversion factor. 24 grams = theoretical yield One cannot calculate the per cent yield since we don't know the actual yield. 343 * 10^(23)"molecules" Your strategy her will be to use the molar mass of aspirin to determine how many moles you have in that sample use Avogadro's number to convert the number of moles to number of molecules So, aspirin, "C"_9"H"_8"O"_4, has a molar mass of "180. calculate the total mass of aspirin in a 500-tablet bottle in grams and ounces. Mixture heated for 10 mins. Dilution refers to make a lower concentration solution from higher concentrations. Assume the aspirin tablets are pure acetylsalicylic acid, K a = 3. This handy calculator can help determine how much of a liquid medication to give your guinea pig. The EMM is the mass of sample in mg which produces one mmole of H + ions upon titration. From the mass of the four tablets you weighed, calculate the average mass of a tablet. Tablet tensile strength is supposed to decrease when particle size increases due to less available surface for binding. If aspirin is taken at high doses and for a long time, it can slowly damage this layer. Show a sample calculation. so this is what I did. 1 mg/tablet, measured from multiple trials by several different groups. 725 × 180 g = 130. 159g (I'm not sure if you meant to write 1. You may find that excessive air swallowing also causes hiccups. The mass is the have dose. Aspirin was first sold as a powder.
