- A solution is formed by mixing 1 gal ethanol with 10 gal gasoline. Identify the solvent and the solute.arrow_forwardClassify the following solutions as unsaturated, saturated, or supersaturated: a.A solution to which a small piece of solute is added, and it dissolves. b.A solution to which a small piece of solute is added, and much more solute comes out of solution. c.The final solution resulting from the process in part b.arrow_forwardCalculate the concentration in (v/v) of the following solutions: a. 200.mL of solution contains 15mL of alcohol. b. 200.mL of solution contains 15mL of any soluble liquid solute. c. 8.0fluidounces of oil is added to 2.0gallons(256fluidounces) of gasoline. d. A solution of alcohol and water is separated by distillation. A 200.-mL sample gives 85.9mL of alcohol.arrow_forward
- A large beaker contains 1.50 L of a 2.00 M iron(III) chloride solution. How many moles of iron ions are in the solution? How many moles of chloride ions are in the solution? You now add 0.500 L of a 4.00 M lead(II) nitrate solution to the beaker. Determine the mass of solid product formed (in grams).arrow_forwardA student was given a 1.6240-g sample of a mixture of sodium nitrate and sodium chloride and was asked to find the percentage of each compound in the mixture. She dissolved the sample and added a solution that contained an excess of silver nitrate. The silver ion precipitated all of the chloride ion in the mixture as silver chloride. It was filtered, dried, and weighed. Its mass was 2.056g. What was the percentage of each compound in the mixture?arrow_forwardAn experiment in a general chemistry laboratory calls for a 2.00-M solution of HCl. How many mL of 11.9 M HCl would be required to make 250 mL of 2.00 M HCl?arrow_forward
- How do we define the mass percent composition of a solution? Give an example of a solution, and explain the relative amounts of solute and solvent present in the solution in terms of the mass percent composition.arrow_forwardCalculate the concentration in (w/w) of the following solutions: a. 20.0g of solute is dissolved in enough water to give 150.mL of solution. The density of the resulting solution is 1.20g/mL. b. A 10.0-mL sample with a density of 1.10g/mL leaves 1.18g of solid residue when evaporated. c. A 25.0-g sample of solution on evaporation leaves a 1.87-g residue of MgCl2.arrow_forwardCalculate the number of moles and the mass of the solute in each of the following solutions: (a) 2.00 L of 18.5MH2SO4, concentrated sulfuric acid (b) 100.0 mL of 3.8105MNaCN, the minimum lethal concentration of sodium cyanide in blood serum (c) 5.50 L of 13.3 MH2CO, the formaldehyde used to fix tissue samples (d) 325 mL of 1.8106MFeSO4, the minimum concentration of iron sulfate detectable by taste in drinking waterarrow_forward
