Average and UncertaintyThe molar mass of an unknown compound was determined in three repeat experiments. The molar masses obtained were 82.23,81.55 and 82.00 g/mol.Assume the uncertainty in the average value to be the half range.Enter the average value and its uncertainty, both rounded to the appropriate number of digits (according to the Rules outlined inthe Chem121 Lab Manual Appendix).g/mol

Step 1: Calculate the average of the obtained molar masses. We will use the formula for average…
