0.811 M is the molar concentration of a 252.6 ml aqueous solution prepared with 70.3 g of sugar.
<h3>Define molarity of a solution.</h3>Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution.
Given data:
252.6 mL = 0.2526 L
Next, we shall determine the number of moles of the sugar. This can be obtained as follow:
Molar mass of sugar = 342.30 g/mol.
Mass of sugar = 70.3 g
Mole of sugar =?
Mole =
Mole =
Mole of sugar = 0.205 mole
Finally, we shall determine the molar concentration of the sugar. This can be obtained as follow:
Mole of sugar = 0.205 mole
Volume = 0.2526 L
Molarity =?
Molarity =
Molarity =
Molarity = 0.811 M
Therefore, the molar concentration of the solution is 0.811 M

Explanation:
Hello,
In this case, since you have both the final and initial volume for the titration procedure, clearly, the used volume is computed by the subtraction between them, since it accounts for the employed volume of the base, it turns out:
