Alcoholic beverages come in many different concentrations denoted by their weight percent (w/w). If a beer is marked as 4.0%, it means there are 4.0 grams of ethanol (C2H6O) in every 100.00 grams of solution. Assuming this solution has a density of 1.00 g/mL, what is the molar concentration of this solution? Give your answer in in decimal format. When entering units, use proper abbreviated units with proper capitalization.
One student measured 25 cm3 of a 1.06 g / dm3 sodium carbonate solution. Calculate the mass of sodium carbonate in mg present in the measured volume.
1a. Medical saline typically consists of 4.50 g of NaCl in 500.0 mL of solution. What is the molarity of this solution? What is the molality of this solution? (Use the density of water = 1 g/mL; for this question, since the concentration is dilute you may assume that the added NaCl does not result in a change in volume when it is added to water.) Do your answers make sense? Would either of these values potentially depend on temperature? 1b. Stomach acid is essentially a solution of hydrochloric acid (HCl). When first secreted, stomach acid has a concentration of roughly 0.160 M HCl. How many moles of HCl are present in 50.0 mL of stomach acid? 1c. If 5.0 mL of saline is introduced to 15 mL of stomach acid. What is the mole fraction of NaCl? What is the mole fraction of HCl? (In your calculations, use the molarities from parts (a) and (b) above).
What is the freezing point of a ethanol solution if that same solution boils at 79.5 ℃? The normal boiling point and freezing point of pure ethanol (C2H5OH) are 78.29 ℃ and -114.2 ℃, respectively. For ethanol, Kb = 1.23 ℃/m and Kf = 1.99 ℃/m.Please enter your response in standard notation to one decimal place.
