Show the calculation of the molecular weight for the following two compounds, reporting your answer to 2 places after the decimal. Al2(CO3)3 Al2(CO3)3 Al2 = 2 x 26.98 = 53.98 3C = 3 x 12.01 = 36.03 9O = 9 x 16.00 = 144 Ans: 243.01 C8H6NO4Cl C8H6NO4CI C = 8 x 12.01 = 96.08 H= 6 x 1.00 = 6 NO = 4 x 259.10 = 1036.4 CI = 35.45 = 35.45 Ans : 1173.93 -4.0 points Instructor Comments Calculation error in the first compound.
