a) the density of an unknown compound made from sulfur and oxygen is 2.47 x 10^-3 g/mL at 23 C and 76 kPa. what are the possible molecular formulas for the compound?
b) according to the adiabatic process, we can define the suitable equation pV=constant. derive an expression that defines the work done using this relation for an adiabatic process. If the initial and final temperatures for the process are T1 and T2, is the work identical to work (adiabtic)= Cv (T2-T1)
