Lab #14 Questions: 1) Is your value of R greater of less than the accepted value of R? Convert  your value of R into ones that have units of J mol -1 K -1  and calories mole -1 K- 1 My   value of R is greater than the value of the accepted value of R.   2) Give your reasons why your values of R do not agree with the accepted  values  One reason why the R constant was different than the accepted value was  because the water temperature measured might have been lower (hotter) than  the normal room temperature it was supposed to be at.     3) If the endometer is not resting on the bottom of the beaker, how would that  affect your results? The measurement of the difference in water levels would have been inaccurate  and therefore leading to the inaccuracy of the Partial Pressure of H 2 .   4) What is the percentage error in your results if the temperature you record  is 10 degrees too high or too low?
