1) Concentration: If 23.7g of NaOH are dissolved into 124.2g of water for form a solution with volume of 137.7mL, calculation the mass percent and molarity of this solution. 2) Dilution: You are growing yeast and your 45% glucose solution is too concentrated. You must dilute it to create 125mL of a 13% glucose solution. How many mL of the 45% solution should you start with? 3) Like Dissolves Like: Identify the following pairs as soluble or insoluble in each other a) H20 and C6H14 b) CH4 and C6H14 ) NaCl and H2O d) NaCl and C6H14 4) How many milliliters of a 6.75 M HCI solution are required to react with 18.4 g of magnesium?

A patient has a “cholesterol count” of 214. Like manyblood-chemistry measurements,this result is measured inunits of milligrams per deciliter (mgdL1). Determine the molar concentration of cholesterol inthis patient’s blood, taking the molar mass of cholesterolto be 386.64gmol1. Estimate the molality of cholesterol in the patient’sblood. If 214 is a typical cholesterol reading among men inthe United States, determine the volume of such bloodrequired to furnish 8.10 g of cholesterol.
A pharmacist prepares an isotonic saline solution for intravenous infusion. Instead of preparing a 0.15 M solution, a 1.5 M solution is prepared. What would happen to the red blood cells if this erroneously prepared solution is infused?
Solutions Introduced directly into the bloodstream have to be isotonic with blood; that is, they must have the same osmotic pressure as blood. An aqueous NaCl solution has to be 0.90% by mass to be isotonic with blood. What is the molarity of the sodium ions in solution? Take the density of the solution to be 1.00 g/mL.
In your own words, explain (a) why seawater has a lower freezing point than fresh water. (b) why one often obtains a grainy product when making fudge (a supersaturated sugar solution). (c) why the concentrations of solutions used for intravenous feeding must be controlled carefully. (d) why fish in a lake (and fishermen) seek deep, shaded places during summer afternoons. (e) why champagne fizzes in a glass.
A 12-oz (355-mL) Pepsi contains 38.9 mg caffeine (molar mass = 194.2 g/mol). Assume that the Pepsi, mainly water, has a density of 1.01 g/mL. For such a Pepsi, calculate: (a) its caffeine concentration in ppm; (b) its molarity of caffeine; and (c) the molality of caffeine.
