- Manufacturers of headache remedies routinely claim that their own brands are more potent pain relievers than the competing brands. Their way of making the comparison is to compare the number of molecules in the standard dosage. Tylenol uses 325 mg of acetaminophen (C8H9NO2) as the standard dose, whereas Advil uses 2.00 × 102 mg of ibuprofen (C13H18O2). Find the number of molecules of pain reliever in the standard doses of (a) Tylenol and (b) Advil.arrow_forwardManufacturers of headache remedies routinely claim that their own brands are more potent pain relievers than the competing brands.

Calculate the number of moles in the sample and iron atoms in the sample. (a) moles in the sample moles (b) iron atoms in the sample atomsarrow_forward
- When a particular substance crystallizes, it forms a body-centered cubic unit cell. It has a molecular weight of 100.11 g/mole. The unit cell edge length is 341 pm. Calculate the density of this substance in g/cm3 .arrow_forwardyeasts are able to produce high internal concentrations of glycerol to counteract the osmotic pressure of the surrounding media. suppose that a sample of yeast cells were placed in a 4% sodium chloride solution by weight. The density of solution is at 25 C = 1.02 g/ml, Molecular weight of solute = 58.44 g/mol, i of glycerol = 1 R=0.08205 L-atm/mol-K What is the weight of solute (in grams)? What is the moles of solute? What is the volume of the solution (in liters)? What is the molarity of the solution? What is the value of the temperature to be used to solve for the osmotic pressure of the solution? What is the osmotic pressure of solution At the same temperature, what will be the molar concentration of glycerol considering the computed osmotic pressure of the solution and the normal osmotic pressure inside a yeast cell of 7.3 atmospheres?arrow_forwardIf the osmotic pressure of the blood is within (100 psi) at a temperature of (37°C). How much glucose must be used per (L1) for intravenous purposes so that its osmotic pressure equals the osmotic pressure of the blood. Note that,R = 0.0821 L. atm.

- An old English cookbook carries this recipe for cream of nettlesoup: “Boil stock of the following amount: 1 breakfastcup plus1 teacup plus 6 tablespoons plus 1 dessertspoon. Using gloves,separate nettle tops until you have 0.5 quart; add the tops to theboiling stock. Add 1 tablespoon of cooked rice and 1 saltspoon ofsalt. Simmer for 15 min.” The following table gives some of theconversions among old (premetric) British measures and amongcommon (still premetric) U.S. measures. (These measures justscream for metrication.) For liquid measures, 1 British teaspoon =1 U.S. teaspoon. For dry measures, 1 British teaspoon = 2 U.S. teaspoonsand 1 British quart 1 U.S. quart. In U.S. measures, howmuch (a) stock, (b) nettle tops, (c) rice, and (d) salt are required inthe recipe?arrow_forwardA 100 gal tank is filled with brine containing 60 lb of dissolved salt. Water runs into the tank at the rate of 1 gal/min and the mixture, kept uniform by stirring, runs out at the rate of 2 gal/min. How much salt is in the tank after 1 hr?arrow_forwardA) What is an equation to equate KE and GPE? B) A gas is held in a container of 15 m^3 in volume and a pressure of 5 Pa. If the volume isincreased to 26 m^3 what is the pressure of the gas? c)A syringe has a volume of 5 cm^3 and a temperature of 300 k. Upon heating the syringeexpands to a volume is now 5.5cm^3, what is the temperature of the syringe?arrow_forward
- Seawater has a salinity of 3.5%, meaning that if you boil away a kilogram of seawater, when you're finished you'll have 35 g of solids (mostly NaCI) left in the pot. When dissolved, sodium chloride dissociates into separate Na+ and CI-ions. Calculate the osmotic pressure difference between seawater and fresh water. Assume for simplicity that all the dissolved salts in seawater are N aCl.arrow_forwardA 5.50 L sample of neon at 6.67 atm is added to a 10.0 L cylinder that contains argon. If the pressure in the cylinder is 7.63 atm after the neon is added, what was the original pressure (in atm) of argon in the cylinder? Hint is given in the feedback. Answer: 6.3315 Hint, what pressure would the neon have in the second container if no argon were present?arrow_forwardEvery day, Jill collects one full bucket of water from the well up the hill. The well has a diameter of 0.800 m and a depth of 3.00 m. Currently, only 65.3% of the well is full. If Jill collects one full bucket every day from today, and it takes her 851 days to empty the well, how many pints of water was she collecting per trip? 1 qt = 2 pints, 1 L = 1.06 qt, 1 m3 = 1000 L, V = πr2harrow_forward
