Problem- Suppose that a student doing this experiment ran into some procedural and calculation difficulties. State the effect each of the following would have on the calculated value of R determined from this experiment. Briefly explain. 1) The student neglected to take into accoundt the pressure of water vapor in the system when doing the calculations. 2) The H2O2 solution had decomposed slightly agter standing for a while, so its concentrations was somewhat lower than the laboratory insuctor had reported. 3) The student failed to read the barometric pressure at the time of the experiment. When she read the pressure the next day for use in her calculations, it was .50 in. Hg higher thatn it had been during the experiment.
Solve the above problem and provide steps with explanation
