The viscosity of a chlorofluorocarbon (CFC) was measured by comparing its rate of flow through a long
Question:
The viscosity of a chlorofluorocarbon (CFC) was measured by comparing its rate of flow through a long narrow tube (using Poiseuille formula) with that of argon. For the same pressure differential, the same volume of the CFC passed through the tube in 72.0 s as argon in 18.0 s. The viscosity of argon at 25°C is 208 1P; what is the viscosity of the CFC? Estimate the molecular diameter of the CFC. Take M = 200 g mol-1.
