This is a freeware computer program, designed for professional use.
In this program the uncertainty in the calculated molar mass is given as the absolute maximum error of the result. The calculated uncertainty is always rounded up to one significant figure. It is rounded up because otherwise it may occur as underestimated. Then the molar mass is rounded to the same absolute accuracy as given in the rounded uncertainty.
