American Commercial College of Texas Chemistry Quiz Hello, I have 8 questions! need to solve them as shown in the sample, i’ll upload all the pictures when someone accepts the question, cuz I can only upload 5 atm. 32. A solution of ethanol (C2H5OH) in water is prepared by dissolving 75.0 mL of ethanol
(density = 0.79 g/cm) in enough water to make 250.0 mL of solution. What is the molarity
of the ethanol in this solution?
34. Calculate the concentration of all ions present in each of the following solutions of strong
electrolytes.
a. 0.0200 mole of sodium phosphate in 10.0 mL of solution
b. 0.300 mole of barium nitrate in 600.0 mL of solution
c. 1.00 g of potassium chloride in 0.500 L of solution
d. 132 g of ammonium in 1.50 L of solution
38. If 10. g of AgNO3 is available, what volume of 0.25 M AgNO3 solution can be prepared?
42. How would you prepare 1.00 L of a 0.50-M solution of each of the following?
a. H2SO4 from “concentrated (18 M) sulfuric acid
44. A solution was prepared by mixing 50.00 mL of 0.100 M HNO3 and 100.00 mL of
0.200 M HNO3. Calculate the molarity of the final solution of nitric acid.
