Use the photo as a guide to answer these questions: A. Find the mean molar mass determined by these workers. B. Find the median molar mass. C. Assuming that the currently accepted value for the molar mass of lithium is the true value (state your reference), calculate the absolute error and the percent relative error of the mean value determined by Richards and Willard.
