Answer;

= 0.422 M

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
