CHEMISTRY- molality

posted by .

a sucrose solution was prepared by dissolving 13.5g sucrose in enough water to make 100ml of solution. the density is 1.050gml. calculate molality

  • CHEMISTRY- molality -

    13.5 g sucrose/molar mass = moles

    convert 100 mL to mass.
    mass = volume x density
    mass = 100 mL x 1.050 g/mL = ??g and convert to kg.
    Then molality = moles/kg solvent.

    how do i get the mole fraction?
