In the box provided, write a brief explanation of what assumption is made in order to determine the molecular weight of your unknown solute when it is dissolved in cyclohexane. for which factor in the expression for the freezing point depression do you not collect data?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
