- It is known that acid content has a major effect on theflavor of vinegars, but most cheaper vinegars are diluted similarly to 5% acidity Wt./vol. % is equivalent to gsolute per 100mL solution (so 5% is equivalent to 5 g acid/100 mL solution). a.) First, calculate the approximate molar concentration of acetic acid in the 5% wt./vol vinegar. b.) Next, calculate the expected molarity of acetic acid in the solution upon dilution by a factor of 5. Thank you!You work with two amino acids. Tryptophan (MW=204 Da) and Methionine (MW=149 Da). You make varioussolutions of each amino acid separately and compare them When you compare two solutions at the same percentage concentration (e.g. 1%), there are moremoles of Tryptophan in solution than moles of Methionine because the molecular weight of Tryptophan ishigher. When you compare two 1-liter solutions containing these amino acids at a 10mM concentration, thereis the same number of amino acid molecules in each solutionDetailed calculations on how to prepare the solutions listed below Solution: 50 mL 1 M oxalic acid Oxalic acid Mw = 90.03 g mol-1 Oxalic acid purity = 98% Solution: 10 mL 3 M sulfuric acid Sulfuric acid Mw = 98.079 g mol-1 Sulfuric acid density = 1.84 g mL-1 Sulfuric acid purity = 98% Solution: 10 mL saturated potassium oxalate potassium oxalate (monohydrate used) Mw = 184.23 g mol-1 Solubility of potassium oxalate in water at 25°C = 360 mg mL-1 Solution :20 mL 3% hydrogen peroxide Hydrogen peroxide is commercially available as a 32% solution.
