I need help finding the therotical yield from this video. I got 2.49g for the answer finding the therotical yield I am i correct. please show me how to solve this molar mass 122.12 for benzoic acid the raw data is magensium ground up= 0.60 grams 10ml ehter and bromobenzene dissolved in it 3.25 grams and 2 drops of 1,2 dibromoethane this is the link to the video where it shows the expirement and the data i found https://www.youtube.com/watch?v=yol0hicBMLk

Can someone help me out here? There first time I calculated the theoretical yield for this experiment I got 0.540g with the given values but I actually used the wrong values. I added the new values above and the units used are mols. I can't seem to figure out or remember how I calculated 0.540g with the (3.00x10^-3 mols)(0.0098 mols). Can someone please help me by telling me how to get grams by using the equation (0.002995 mols)(0.0105mols)? I know the value should be relatively close to 0.540g but every time I try to calculate it, my answer is no where near 0.540g. Please answer clearly and concisely. Also please make sure to read the question carefully, thank you!
The stock erythrosine B solution is 8.5 × 10-5 M. Calculate the volume of this solution that you must pipet into a 50-mL volumetric flask, which, when diluted to mark with deionized water, will give a final concentration of 1.7 × 10-5 M. Show your calculation setup.
50.00 cm3 of a 1.5784 mol.dm-3 solution of potassium hydroxide is transferred to an empty 700.00 cm3 volumetric flask. This flask is made up to the mark with distilled water and then shaken well. The concentration of the potassium hydroxide in this second flask is:
ou separated acetanlide from sand and sodium chloride (NaCl) via recrystallization. You separated the recrystallized acetanilide from the dissolved NaCl using a seperatory funnel. You started the separation experiment with 4 g of an impure mixture of NaCl, sand, and acetanilide (MW= 135.17 g/mol) and you collected 3.2 g after the recrystallization experiment.Whats the percent yield?
A student was tasked to perform gravimetric analysis of a soluble sulfate. His unknown sample weighed 0.7543 g. The sample underwentprecipitation using BaCl2 and was digested for overnight. The precipitate was then filtered off to obtain white crystalline precipitate that was collected inan ash less filter paper. In performing constant weighing, he obtained a crucible mass that is 29.9442 g. After burning his samples inside the crucible,the obtained mass was 30.3375 g. Compute for the theoretical % SO3 obtained by the student and the theoretical mass (g) of SO3 that should be obtained by the student using his weighed sample
