How much dinitrogen tetroxide [in grams] was needed?One gram-mole of methyl chloride vapor is contained in a vessel at 100°C and 10 atm.(a) Use the ideal-gas equation of state to estimate the system volume.(b) Suppose the actual volume of the vessel is 2.8 liters. What percentage error results from assuming ideal-gas behavior?What is the change in the chemical potential of a system if 1mole of O2 were added to a system already containing 1mole of O2? Probably the best answer is no change. Why?
- Polycarbonate, PC, is used for aircraft canopies. A batch of this polymer was found to fail prematurely when impacted by a 4 pound bird during qualification studies. You suspect that the problem is due to a molecular weight difference for this particular batch of polymer compared to previous batches. You decide to perform dilute solution viscosity studies to determine the Mol.wt. Assume density is 1.2g/cm3 What solvent would you use?
