1. [H2O2] – molar concentration of 3% m/v hydrogen peroxide solutionThe concentration of hydrogen peroxide stock solution is 3% m/v. Convert this tomolar concentration (mol/L).The unit m/v represents g/mL... so, 3% m/v = 3 g H2O2/100 mL soln 1. The hydrogen peroxide stock solution has a concentration of 3% m/v. PerformCalculation #1 (p. 4) and convert value to a molar concentration (mol/L).2. Perform Calculation #2 (pp. 4-5) and determine the molar concentrations of thehydrogen peroxide and iodine-potassium-iodide solutions after the dilutions describedin Steps 1 and 2 of the procedure ([I]a and [H202]a).

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?
Sodium 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.)
6-16 Answer true or false. (a) Solubility is a physical property like melting point and boiling point. (b) All solutions are transparent—that is, you can see through them. (c) Most solutions can be separated into their components by physical methods such as distillation and chromatography.
In lab you need to prepare at least 100 mL of each of the following solutions. Explain how you would proceed using the given information. a. 2.0 m KCl in water (density of H2O = 1.00 g/cm3) b. 15% NaOH by mass in water (d = 1.00 g/cm3) c. 25% NaOH by mass in CH3OH (d = 0.79 g/cm3) d. 0.10 mole fraction of C6H12O6 in water (d = 1.00 g/cm3)
The Henry's law constant for the solubility of argon gas in water is 1.0103M/atm at 30C. (a) Express the constant in M/mm Hg. (b) If the partial pressure of argon gas at 30C is 693 mm Hg, what is the concentration (in M) of the dissolved argon gas at 30C? (c) How many grams of argon gas can be dissolved in 29 L of water at 693 mm Hg and 30C? (Ignore the partial pressure of water.)
The dispersed phase of a certain colloidal dispersion consists of spheres of diameter 1.0 102 nm. (a) What are the volume (V=43r2) and surface area (A = r2) of each sphere? (b) How many spheres are required to give a total volume of 1.0 cm3? What is the total surface area of these spheres in square meters?
Calculate 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 water
6-54 An industrial wastewater contains 3.60 ppb cadmium Cd2+. How many mg of Cd2+ could be recovered from a ton (1016 kg) of this wastewater?
