    Molar mass glucose = 180.1559 g/mol

    number of moles solute:

    n = m / mm

    n = 180 / 180.1559

    n = 0.999 moles

    number of moles solvent:

    molar mass water = 18.01528 g/mol

    n = m / mm

    n = 162 / 18.01528

    n = 8.992 moles

    Mole fraction total:

    moles solut + moles solvent : 0.999 + 8.992 = > 9.991 moles

    Therefore mole fraction of glucose is:

    fraction molar = moles of solute / moles total

    = 0.999 / 9.991

    => 0.010
