What is the molarity of a solution that contains 289 grams of sugar in a 2 l solution? (molar mass of sucrose is 342.2965g/mol). show your work answer

0.422 mol/L.

Explanation:

M = (no. of moles of glucose)/(volume of the solution (L))

M = (mass/molar mass)of glucose / (volume of the solution (L)).

∴ M = (mass/molar mass)of glucose / (volume of the solution (L)) = (289 g/342.2965 g/mol)/(2.0 L) = 0.422 mol/L.
