Question #195813

A student calculated the molarity of a solution prepared by dissolving 0.730 mol of table sugar (sucrose, C_{12}H_{22}O_{11}) in 1.8x10^3 mL of water as 4.06x10^-4 M C_{12}H_{22}O_{11}.

- 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.

II. The student then takes a 1.00 M stock solution of table sugar (sucrose, C_{12}H_{22}O_{11}) 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.

Expert's answer

1.Valid Molarity =0.347M

2.Valid final molarity =2.91M
