The molecular weight of a substance is determined from the following experimental data.         Weight: 0.145g±0.002g        Number of moles:  0.00266 mol±0.00004 g        Molecular weight: 64.15929 g/mol±?/mol        The molecular weight is calculated by dividing the weight in grams by the number of moles.        Determine the  ± absolute error in the molecular weight.
