An aqueous solution of sucrose (C12H22O11) is prepared by dissolving 7.1800 g in sufficient deionized water to form a 25.00 mL solution. Calculate the molarity of the solution.

Answer 1

Molar mass sucrose = 342 g/mol

molarity = moles solute /liter solution

Moles = 7.1800 g x 1 mol/342 g = 0.02099 moles

liters = 0.02500

molarity = 0.02099 mol/0.025 L = 0.8398 M
