7. Calculate the volume of pure isopropanol in the 50 mL you measured, using the %. Recall that a % solution can be expressed as mL or g per 100 mL solution. 8. Calculate the molecular mass of isopropanol (C3H$O). C. = 12.011 amu x 3 = 36.033 amu This ke may minutes Add = 60.096 gImol H=1,008 annu x 8 = 8.064 amO- O= 15,999 amux 1:15.999 amu 9. Calculate the number of moles of isopropanol added to your ice solution. Pure isopropanol is 16.64 M. on your tmmeter calibetion. r the voline of sollen to earest 0.1ml 10. Calculate the volume of water in your melted ice and isopropanol solution. 9. the cheal 20. the molar 11. Calculate the mass of water in the solution. (Recall that 1.0 mL of pure water has a mass of 1.0 g) Convert your answer to kg. 12. Recall that the freezing point is depressed by -1.86 °C per mole of solute per kg of water. Calculate the theoretical freezing point of the mixture you created. 13. Compare the actual to the theoretical.
