- Specifications for lactated Ringers solution, which is used for intravenous (IV) injections, are as follows to reach 100. mL of solution: 285315 mg Na+ 14.117.3 mg K+ 4.9Q.O mg Ca2+ 368408 mg Cl 231261 mg lactate, C3H5O3 a. Specify the amount of NaCl, KCl, CaCl2 2H2O, and NaC3H5O3 needed to prepare 100. mL lactated Ringers solution. b. What is the range of the osmotic pressure of the solution at 37C, given the preceding specifications?arrow_forwardTable sugar (C12H22O11) or urea [(NH2)2CO] can be used by road crews to melt ice on roads, but solutions of CaCl2 are generally used instead. Assuming equal costs per pound of substance, why is CaCl2 used instead of table sugar or urea?arrow_forwardCalculate the percent by mass of solute in each of the following solutions. 5.00 g of calcium chloride dissolved in 95.0 g of water 1.00 g of calcium chloride dissolved in 19.0 g of water 15.0 g of calcium chloride dissolved in 285 g of water 2.00 mg of calcium chloride dissolved in 0.0380 g of waterarrow_forward
- A sample of water contains 0.010 ppm lead ions, Pb2+. (a) Calculate the mass of lead ions per liter in this solution.(Assume the density of the water solution is 1.0 g/mL.) (b) Calculate the mass fraction of lead in ppb.arrow_forwardSodium chloride (NaCl) is commonly used to melt ice on roads during the winter. Calcium chloride (CaCl2) is sometimes used for this purpose too. Let us compare the effectiveness of equal masses of these two compounds in lowering the freezing point of water, by calculating the freezing point depression of solutions containing 200. g of each salt in 1.00 kg of water. (An advantage of CaCl2 is that it acts more quickly because it is hygroscopic, that is. it absorbs moisture from the air to give a solution and begin the process. A disadvantage is that this compound is more costly.)arrow_forwardCompare Which of the following solutions has thehighest concentration? Rank the solutions from thegreatest to the smallest boiling point depression. Explainyour answer. a. 0.10 mol NaBr in 100.0 mL solution b. 2.1 mol KOH in 1.00 L solution c. 1.2 mol KMnO4 in 3.00 L solutionarrow_forward
- An experiment calls for 100. mL of 1.25 M HC1. All that is available in the lab is a bottle of concentrated HC1, whose label indicates that it is 12.1 M. How much of the concentrated HC1 would be needed to prepare the desired solution?arrow_forwardGraph Table 14.10 shows solubility data that was collectedin an experiment. Plot a graph of the molarity ofKI versus temperature. What is the solubility of KI at55°C?arrow_forward
