What is the molarity of a solution that contains 289 g of sugar in a 2 L solution?

Question

The molar mass of sucrose being 342.2965 and please show work done.

Answer 1

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

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
