CHEM 1201 : Quiz 2 Review 2
Document Summary
Page 1: how many grams of solute are present in 59. 9 ml of 0. 849 m na3po4, give the concentration of each ion present in the solution formed by mixing together the two solutions described below: 57. 5 ml of 0. 178 m na2co3 and 10. 6 ml of 0. 452 m na2co3: ethanol, c2h6o, is a substance used in the manufacture of alcoholic beverages. Ethanol is a water-soluble liquid with a density of 0. 790 g/ml at 25 oc. Calculate the molarity of a solution of ethanol made by dissolving 60. 0 ml of ethanol at 25 oc in enough water to make 900 ml of solution. Page 2: a sample of solid mg(oh)2 was stirred in water at a certain temperature until the solution contained as much dissolved mg(oh)2 as it could hold. A 650-ml sample of this solution was withdrawn and titrated with 0. 00579 mhno3. It required 20. 7 ml of the acid solution for neutralization.
