Asucrose solution is prepared to a final concentration of 0.190 m . convert this value into terms of g/l, molality, and mass % (molecular weight, mwsucrose = 342.296 g/mol ; density, ρsol′n = 1.02 g/ml ; mass of water, mwat = 955.0 g ). note that the mass of solute is included in the density of the solution.

The strength of the sucrose solution is 65.03624 g/L.

Molality of the solution is 0.1989 mol/kg.

Mass percentage of the solution is 6.37%

Explanation:

Strength of the sucrose solution

Molarity of the sucrose solution = 0.190 M = 0.190 mol/L

Molar mass of sucrose = 342.296 g/mol

Strength of the solution =  Molarity of the solution × Molar mass of the solute

Strength of the sucrose solution =

=

Molality of the solution:

Moles of sucrose in 1L solution = 0.190 moles

Mass of water = 955.0 g = 0.9550 kg

Molality of the solution is:

Mass percentage of the solution:

Density iof the solution =

Mass of solution = Mass of solute + Mass of water

Volume of solution = 1L = 1,000 mL

Mass of solution = 1.02 g/mL × 1,000 mL = 1,020 g

Mass of solute + Mass of water = 1,020 g

Mass of solute = 1,020 g - 955.0 g = 65.0 g

Mass percentage:

Mass percentage of the solution is 6.37%
