McDalton-Mass calculator Dalton Learning

McDalton Learning Edition 1.0This is a freeware computer program, designed for learning purposes, to calculate molar or formula masses. For this reason the calculations are shown together with the result. Most textbooks include an Atomic mass table with values rounded to one or two decimals. For compatibility with Answers on examples given in those textbooks McDalton Learning Edition includes the option to use a fixed number of decimals. This may also increase the Readability of the output. On recommendation by The International Union of Pure and Applied Chemistry, IUPAC, atomic weights of the elements are taken from the review Atomic weights of the elements 2007, published in Pure Appl. Chem. 78(11), 2051-2066, 2006 and Aug 2007 release. As Default all figures are used in the calculations. If you enter the formula of just one element the recommended atomic weight is displayed.
