Question

please show all work when 5.0 g of an unknown substance is dissolved in 100.0g ofwater, the freezing point of the solution decreases by 1.5 celsius.what is the molar mass of the unknown substance if the compounddoes not dissociate to form ions in solution, that is , i=1? please show all work when 5.0 g of an unknown substance is dissolved in 100.0g ofwater, the freezing point of the solution decreases by 1.5 celsius.what is the molar mass of the unknown substance if the compounddoes not dissociate to form ions in solution, that is , i=1?

Explanation / Answer

OR you can write it out like this ?T = K • molality molality = ?T/K molality = 1.5°C/1.86 °C•kg/mole = 0.81 mol/kg 5.0 g/Mmol/0.100kg = 0.81 mol/kg 50. g/.81mol = Mmol Mmol = 62 g/mol
