The calculated molar mass of this program given the uncertainty of the absolute maximum error in the results. The calculated uncertainties are rounded up each time an important figure. Because otherwise, as may occur in this light is rounded up. Then, given the same absolute uncertainty of molar mass round to be rounded.

Example it will open. PbO is calculated as the molar mass of 207.2 + 15.9994 = 223.1994 and the molar mass uncertainty is calculated as 0.1 + 0.0003 = 0.1003. Uncertainty in the first decimal figure, and therefore only significant molar mass is 223.2 ± 0.2 for the best value and of course, as explained above are rounded to uncertainty as before is given.
