- You want to prepare a 1.0 mol/kg solution of ethyleneglycol, C2H4(OH)2, in water. Calculate the mass of ethylene glycol you would need to mix with 950. g water.arrow_forwardHow would you prepare from the solid and pure water (a) 0.400 L of 0.155 M Sr(OH)2? (b) 1.75 L of 0.333 M (NH4)2CO3?arrow_forwardWhat is the molarity of a glucose (C6H12O6) solution prepared from 55.0 mL of a 1.0 M solution that is diluted with water to a final volume of 2.0 L?arrow_forward
- Insulin is a hormone responsible for the regulation of glucose levels in the blood. An aqueous solution of insulin has an osmotic pressure of 2.5 mm Hg at 25C. It is prepared by dissolving 0.100 g of insulin in enough water to make 125 mL of solution. What is the molar mass of insulin?arrow_forwardWhat mass of a 4.00% NaOH solution by mass contains 15.0 g of NaOH?arrow_forwardThe freezing point of a 0.21 m aqueous solution of H2SO4 is -0.796C. (a) What is i? (b) Is the solution made up primarily of (i) H2SO4 molecules only? (ii) H+ and HSO4- ions? (iii) 2H+ and 1SO42- ions?arrow_forward
- What kinds of solute particles are present in a solution of an ionic compound? Of a molecular compound?arrow_forwardSilver ions can be found in some of the city water piped into homes. The average concentration of silver ions in city water is 0.028 ppm. (a) How many milligrams of silver ions would you ingest daily if you drank eight glasses (eight oz/glass) of city water daily? (b) How many liters of city water are required to recover 1.00 g of silver chemically?arrow_forwardOne mole of CaCl2 is represented as where represents Ca and represents Cl. Complete the picture showing only the calcium and chloride ions. The water molecules need not be shown. What is the molarity of Ca2+? of Cl-?arrow_forward
- Lead poisoning has been a hazard for centuries. Some scholars believe that the decline of the Roman Empire can be traced, in part, to high levels of lead in water from containers and pipes, and from wine that was stored in leadglazed containers. If we presume that the typical Roman water supply was saturated with lead carbonate, PbCO3 (Ksp = 7.4 1014), how much lead will a Roman ingest in a year if he or she drinks 1 L/day from the container?arrow_forwardInsulin is a hormone that controls the use of glucose in the body. How many moles of insulin are required to make up 28 mL of 0.0048 M insulin solution?arrow_forwardOne mole of Na2S is represented as where represents Na and represents S. Complete the picture showing only the sodium and sulfide ions. The water molecules need not be shown. What is the molarity of Na+? of S2-?arrow_forward
