Density of Zinc: Consider the data and results from the density of zinc determination. Now focus on the average absolute error associated with the calculated average density of zinc. Which measurement contributes the most relative error to this value? Given that measurement and its associated absolute error, is the calculated average absolute error reasonable and why? What aspect of the experiment limited the measurements the most?

1-arr In a study of the gas phase decomposition of phosphine at 120 °C PH3(g)- →1/4 P4(g) + 3/2 H2(g) the concentration of PH3 was followed as a function of time. It was found that a graph of In[PH3] versus time in seconds gave a straight line with a slope of -2.50×10² s1 and a y-intercept of -3.24. Based on this plot, the reaction i v O order in PH, and the half life for the reaction is seconds. zero first second
