Question
(8PTS) Richards and Willard determined the molar mass of lithium and collected the following data. Experiment Molar mass, g/mol 1 6.9391 2 6.9407 3 6.9409 4 6.9399 5 6.9407 6.9391 7 6.9406 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.
