A 4.14 m solution of the solute methylene chloride dissolved in the solvent ethanol is available. Calculate the mass ( kg ) of the solution that must be taken to obtain 1487 g of methylene chloride.
CH2Cl2-1327 (kg/m^3)
C2H5OH-789.3 (kg/m^3)

  • chemistry -

    m = molality = moles solute/kg solvent.
    If we want 1487 g CH2Cl2, that is
    1487 g x (1 mole/molar mass CH2Cl2) = ?? moles.
    So how many kg must take of the solution to obtain ?? moles? I get something like 4 kg. I don't know why you have the density given.
