help me out please
lland 2.) You have a new set of automobile radiators to test, but had forgotten to obtain antifreeze/radiator coolant to do the test. Let's say your test radiators are cheap/disposable. Based on the material that you covered in Chapter 8 (colligative properties), you know that you can use salt or sugar to increase the boiling point or lower the freezing point. Therefore, you attempt to do a quick-and-crude test on the radiators using ordinary Table Sugar...
