Concept explainers
Ethylene glycol is the main component in automobile anti-freeze. To monitor the temperature of an auto cooling system, you intend to use a meter that reads from 0 to 100. You devise a new temperature scale based on the approximate melting and boiling points of a typical antifreeze solution (−45°C and 115°C). You wish these points to correspond to 0°A and 100°A, respectively.

- 1.87 A solution of ethanol in water has a volume of 54.2 mL and a mass of 49.6 g. what information would you need to look up and how would you determine the percentage of ethanol in this solution?arrow_forwardPotassium sulfate has a solubility of 15 g/ 100 g water at 40C. A solution is prepared by adding 39.0 g of potassium sulfate to 225 g of water, carefully heating the solution, and cooling it to 40C. A homogeneous solution is obtained. Is this solution saturated, unsaturated, or supersaturated? The beaker is shaken, and precipitation occurs. How many grams of potassium sulfate would you expect to crystallize out?arrow_forwardSuppose that you are closing a cabin in the north woods for the winter and you do not want the water in the toilet tank to freeze. You know that the temperature might get as low as 30. C, and you want to protect about 4.0 L water in the toilet tank from freezing. Calculate the volume of ethylene glycol (density = 1.113 g/mL; molar mass = 62.1 g/mol) you should add to the 4.0 L water.arrow_forward
- This year, like many past years, you begin to feel very sleepy alter eating a large helping of Thanksgiving turkey. Some people attribute this sleepiness to the presence of the amino acid tryptophan in turkey. Tryptophan can be used by the body to produce serotonin, which can calm the brains activity and help to bring on sleep. a. What mass in grams of tryptophan is in a 0.25-lb serving of turkey? (Assume tryptophan accounts for 1.0% of the turkey mass.) b. What mass in grams of tryptophan is in 0.25 quart of milk? (Assume tryptophan accounts for 2.0% of milk by mass and that the density of milk is 1.04 kg/L.)arrow_forwardYou want to cook some raw noodles to make a pasta dish for supper. So, you turn on the gas stovetop (which uses a flame), place a large pot of water over the flame, wait for the water to boil, place the noodles ¡n the boiling water for 11 minutes, and then drain the water from the noodles. Identify one example of a physical change and one example of a chemical change in this process. Explain your answer for each.arrow_forwardTo prepare olives for consumption and remove their bitterness, powdered soda (sodium hydroxide, NaOH) is usually used in the industry, which is added to the water in which the olives are found (this method should not be used at home if we had olive trees because soda is highly corrosive and very dangerous, in this case we should use table salt). Normally 1 kilogram of soda is added for every 3 liters of water (weighing 3 kg, remember that the density of water is 1 g/mL).Thus, 4 kg of solution were obtained, and the density of this solution was determined experimentally to be 1.25 g/mL. a) Calculate what volume of solution is obtained. (Remember that d = m/V). b) What will be the concentration of that solution expressed in grams of solute dissolved in each liter of solution? c) What will be the concentration expressed in % by mass (or weight)? • If we separate a ladle (100 mL) of that solution. d) What will be the concentration of soda in the liquid in the ladle? e) How many grams of…arrow_forward
