A soft drink contains an unknown mass of citric acid, C3H5O(COOH)3. It requires 6.42 mL of 9.580 × 10−2-M NaOH to neutralize the citric acid in 10.0 mL of the soft drink. C3H5O(COOH)3(aq) + 3 NaOH(aq) → Na3C3H5O(COO)3(aq) + 3 H2O(ℓ) Determine which step in these calculations for the mass of citric acid in 1 mL soft drink is incorrect? Why? n (NaOH) = (6.42 mL)(1L/1000 mL)(9.580 × 10−2 mol/L) n (citric acid) = (6.15 × 10−4 mol NaOH) × (3 mol citric acid/1 mol NaOH) m (citric acid in sample) = (1.85 × 10−3 mol citric acid) × (192.12 g/mol citric acid) m (citric acid in 1 mL soft drink) = (0.354 g citric acid)/(10 mL soft drink) Determine the correct result.
Consider the reaction between 1.0 L of 3.0 M AgNO3(aq) and 1.0 L of 1.0 M CuCl2(aq), according to the equation: 2AgNO3(aq)+CuCl2(aq))2AgCl(s)+Cu(NO3)2(aq) Which of the following will increase the amount of AgCl(s) produced? a. Adding another 1.0 L of 3.0 M AgNO3(aq) h. Adding another 1.0 L of 1.0 M CuCl2(aq) c. Adding 1.0 L of water to the original AgNO(aq) solution d. Allowing all of the water to evaporate from the resulting solution e. At least two of the above will increase the amount of AgCl(s) produced.
Dilution means adding water to something so that the ratio of solute to solvent is less than in the original solution. Some people say, “Dilution is the solution to pollution.” Do you think this statement true? Could you ever add enough water so that there would be no drink mix—that the water would be the same as in cup #6, pure water? Do you think you could you ever add enough water to a pollutant to make it disappear completely? Why or why not?
About 10.0 g of an unknown sample was dissolved in 500 mL aqueous solution. The solution has an osmotic pressure of 7.8 x 10-3 atm at 22 degrees celsius. What is the molar mass of the sample? a. 3.2 x 104 a. 1.6 x 104 a. 5.7 x 104 a. 6.2 x 104
