Chapter 1, Problem 1.126E

What volume of a 0.20MK2SO4 solution contains 57 g of K2SO4?

Every 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.

Calculate the concentration in (v/v) of the following solutions: a.250.mL of solution contains 15.0mL of acetone. b.250.mL of solution contains 15.0mL of any soluble liquid solute. c.1.0 quart of acetic acid is put into a 5- gallon container, and enough water is added to fill the container. d.A solution of acetone and water is separated by distillation. A 300.-mL sample gives 109mL of acetone.

Calculate the following: a. The number of grams of Li2CO3 in 250.mL of 1.75M Li2CO3 solution b. The number of moles of NH3 in 200.mL of 3.50M NH3 solution c. The number of mL of alcohol in 250.mL of 12.5(v/v) solution d. The number of grams of CaCl2 in 50.0mL of 4.20(w/v)CaCl2 solution
