Question

In an analysis, you need enough product to weigh accurately. If a tablet
sample contains approximately 15 mg of Fe (MW= 55.845 g/mol), how
many tablets should you analyze to produce 0.25 g of Fe_20_3 (MW=
159.69 g/mol)? *

In lab, you add 2.074 g salicylic acid to a 125 mL Erlenmeyer flask, as listed in the procedure. You carefully add 4.0 mL acetic anhydride and have your TA add 5 drops of sulfuric acid. After completing the synthesis and filtering, you place the crystals to dry on an evaporating dish that weights 21.682 g. After drying, the crystals and evaporating dish weigh 23.034. Calculate the percent yield of aspirin.
To prepare standard KHP ( M.W.= 204.22 ) solution for the KHP lab, you weighed out 0.9539 ( ± 0.0002 ) g solid KHP that was subsequently dissolved in 500.00 ( ± 0.03) mL of water completely. Then 18.45 (± 0.02) mL of this KHP solution were needed to neutralize 25.00 (± 0.04) mL of NaOH solution. What is the molarity of NaOH in the solution, with its absolute and relative uncertainties ?
A 1.00 L bottle of wine, labeled as 8.5% (by volume) ethanol, is found to have a defective seal. Analysis of 1.00 mL showed that there were 0.0274 grams of acetic acid in that 1.00 mL. The density of ethanol is 0.816 g/mL and the density of water is 1.00 g/mL. What mass of oxygen must have leaked into the bottle? I'm pretty good with conversions and molarity and stuff but I mainly need to know how to even go about answering this question.
