Concept explainers
(a)
Interpretation:
The mass of the solution which contains
Concept introduction:
The concentration of any solution can be expressed in different ways, such as molarity, molality, mole fraction and mass by mass percentage. In mass by mass percent concentration, mass of the solute present in total volume of solution is expressed as a percentage.

- What kinds of solute particles are present in a solution of an ionic compound? Of a molecular compound?arrow_forwardInsulin 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_forwardExplain why the distinction between solute and solvent is not clear for some solutions.arrow_forward
- Use the term soluble, insoluble, or immiscible to describe the behavior of the following pairs of substances when they are shaken together: a.25mL of cooking oil and 25mL of vinegar the resulting mixture is cloudy and gradually separates into two layers. b.25mL of water and 10mL of rubbing alcohol the resulting mixture is clear and colorless. c.25mL of chloroform and 1g of roofing tar the resulting mixture is clear but dark brown in color.arrow_forwardA 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.arrow_forward6-21 Are mixtures of gases true solutions or heterogeneous mixtures? Explain.arrow_forward
