- 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 solutionarrow_forwardWhat happens if you add a very small amount of solid salt (NaCl) to each beaker described below? Include a statement comparing the amount of solid eventually found in the beaker with the amount you added: a a beaker containing saturated NaCl solution, b a beaker with unsaturated NaCl solution, c a beaker containing supersaturated NaCl solution. A saturated sodium chloride solution.arrow_forwardCalculate 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.arrow_forward
- Calculate the molarity of the following solutions: a. A sample of solid Na2SO4 weighing 0.140g is dissolved in enough water to make 10.mL of solution. b. A 4.50-g sample of glucose (C6H12O6) is dissolved in enough water to give 150.mL of solution. c. A 43.5-g sample of K2SO4 is dissolved in a quantity of water, and the solution is stirred well. A 25.0-mL sample of the resulting solution is evaporated to dryness and leaves behind 2.18g of solid K2SO4.arrow_forwardCalculate the concentration in (w/v) of the following solutions: a. 150.mL of solution contains 7.50g of dissolved solid Na2SO4. b. 150.mL of solution contains 7.50g of any dissolved solid solute. c. 350.mL of solution contains 30.7g of dissolved solid solute.arrow_forwardThe specific gravity of a solution of KCl is greater than 1.00. The specific gravity of a solution of NH3 is less than 1.00. Is specific gravity a colligative property? Why, or why not?arrow_forward
