Chapter 14 Solutions
FOUND.OF COLLEGE CHEMISTRY
- What mass of a 4.00% NaOH solution by mass contains 15.0 g of NaOH?arrow_forwardWhat mass of HCl is contained in 45.0 mL of an aqueous HCl solution that has a density of 1.19 g cm-3 and contains 37.21% HCl by mass?arrow_forwardMixtures of gases are always true solutions. True or false? Explain why.arrow_forward
- A solution is 0.1% by mass calcium chloride. Therefore, 100. g of the solution contains g of calcium chloride.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_forwardEvery pure substance has a definite and fixed set of physical and chemical properties. A solution is prepared by dissolving one pure substance in another. Is it reasonable to expect that the solution will also have a definite and fixed set of properties that are different from the properties of either component? Explain your answer.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_forwardFluoridation of city water supplies has been practiced in the United States for several decades. It is done by continuously adding sodium fluoride to water as it comes from a reservoir. Assume you live in a medium-sized city of 150,000 people and that 660 L (170 gal) of water is used per person per day. What mass of sodium fluoride (in kilograms) must be added to the water supply each year (365 days) to have the required fluoride concentration of 1 ppm (part per million)that is, 1 kilogram of fluoride per 1 million kilograms of water? (Sodium fluoride is 45.0% fluoride, and water has a density of 1.00 g/cm3.)arrow_forward
