1. Solve the following queries. Make sure you show full procedure using conversion factors if applicable a) Three solutions were produced: 50 g of C4H8O4 in 2 L water, 50 g of C8H1407 in 2 L water, and 50 g of C12H20O10 in 2 L solution. What are the molalities of these solutions? b) A sucrose solution was prepared by dissolving 13.5 g C12H22O11 in sufficient water to make exactly 100 mL, which was then found to have a density of 1.050 g/mL. Compute the molar concentration and the molality of the solution. c) What is the volume of concentrated H₂SO4 (density 1.835 g/cm³, 93.2% H₂SO4 by weight) required to make up 500mL of 3.00N acid solution.

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.
