II. The student then takes a 1.00 M stock
solution of table sugar
(sucrose, C12H22011) 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.

Answer:

0.244 M.

Explanation:

From the question given above, the following data were obtained:

Molarity of stock solution (M₁) = 1 M

Volume of stock solution (V₁) = 0.305 L

Volume of diluted solution (V₂) = 1.25 L

Molarity of diluted solution (M₂) =?

The molarity of the diluted solution can be obtained by using the dilution formula as illustrated below:

M₁V₁ = M₂V₂

1 × 0.305 = M₂ × 1.25

0.305 = M₂ × 1.25

Divide both side by 1.25

M₂ = 0.305 / 1.25

M₂ = 0.244 M

Thus, the molarity of the diluted solution is 0.244 M
