    Answer;

    = 0.422 M

    Explanation;

    Molarity or concentration is the number of moles of a solute in 1 liter of a solution.

    Therefore; Molarity = n/V; where n is the number of moles and V is the volume of the solution in L.

    Number of moles = Mass/molar mass

    = 289 g/342.2965g/mol

    = 0.844 Moles

    Therefore;

    Molarity = 0.844 moles / 2L

    = 0.422 M
