What is the molarity if a solution that contains 289 grams of sugar in a 2 liter solution? ? molar mass of source is 342.2965g/mol

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

56 moles of   lieter in chemistry

the answer is d. 74.02
