MOLAR-PROPORTION ================ What: A program that calculates the mass of a certain substance in a reaction formula. Ex: 2 mol H2 <==> 1 mol O2 <==> 2 mol H2O reaction: 2H2 + O2 => 2H2O We know the mass of the water we got but we want to know how much of the hydrogen weights that includes the reaction. The water has the mass 1000g. MASS OF SUBST. A:? 1000 X:? 2 Y:? 2 FORMULA (A): C:? 0 H:? 2 O:? 1 N:? 0 FORMULA (B): C:? 0 H:? 2 O:? 0 N:? 0 MASS OF SUBST. B= 111.90053286 SUBST. QUANTITY OF SUBST. B= 55.5062166963 Lets check: M*n=m => 2.02*55.5=112.11 g -almost the same. Size: 317 Bytes Of: B.
