A student calculated the molarity of a solution prepared by dissolving 0.730 mol of table sugar (sucrose, C12H22O11) in 1.8×10^3 mL of water as 4.06×10^-4 M C12H22O11.
Explain the student’s calculation error and explain how the student should solve for the correct value of molarity. Show a valid calculation for the molarity.
The student then takes a 1.00 M stock solution of table sugar (sucrose, C12H22O11) and mixes 0.305 L of stock solution with additional distilled water to create a dilute solution with a total volume of 1.25 L.
Explain how the student can determine the molarity of the resulting solution. Show a valid calculation for the final molarity.
