The ethyl alcohol content of beers produced is reported as ABV or alcohol by volume (vol/vol) If the density of ethyl alcohol at room temperature is 0.7893 grams/mL, what is the percent of ethyl alcohol in 4.50% beer expressed as percent (wt/vol)
When concentrated nitric is sold, the label contains no mention of the molarity of the acid. Instead, the label normally lists the concentration of nitric acid as a wt/wt percent and gives the specific gravity of the solution. If the solution is 68.0 (wt/wt %) and nitric acid and has a specific gravity of 1.41 kg/L, calculate the molarity of 68.0 % concentrated nitric acid. FW HNO3=63.01g/mol
Analysis of product: Calculate the percent recovery based on the amount of tea originally used and a final mass of 0.20g of caffeine obtained. Compare this value against a literature search about the approximate caffeine content by percent in black tea. Given: the observed melting point of the product crystals is 230oC-235oC -10 tea bags (black tea, contains ~45mg caffeine/bag) -total mass is 21.10g of the loose black tea
