How many grams of sucrose (C12H22O11) must be dissolved in 60 g water to make a solution in which the mole fraction of sucrose is 0.2? Answer in units of g.

  • Chemistry -

    let moles C12H22O11 = x
    moles H2O = 60/18 = 3.33 but check that.
    Xsucrose = x/total moles and
    0.2 = x/(x+3.33)
    solve for x = moles sucrose.
    g = mols x molar mass.
    Check my work.
