In Part B of this experiment, you need to add a known amount of the liquid unknown to your water-ice mixture. You want the concentration of the liquid unknown in solution to be around 2 m. Let's estimate how much liquid unknown you should add.
Assuming that there is about 100g of liquid water in the solution, how many moles of liquid unknown will be present in a 2 m solution? Also, assuming that the molar mass of the liquid unknown is about 50g/mol, calculate the approximate mass of liquid unknown that should be added to your water-ice mixture.
