Molecular Calculator features:
103 elements and all their stable isotopes.
Easy button-access to 24 of the most common elements. Other elements can be inserted by
using the keyboard - simply touch the formula edit field and keyboard will pop up.
Argumented input:
By inserting 2mNaCl  (2 moles of NaCl) it calulates  the mass in grams.
By inserting 2gNaCl  (2 grams of NaCl) it calculates the mol amount.
By inserting 2mC,CH3COOH (a  total of 3 moles of C in the compund) it calculates both moles and mass for the compund.
By inserting 2gC,CH3COOH (a  total of 3 grams of C in the compund) it calculates both moles and mass for the compund.
Structural formulas such as  CH3-CH2-CH2-COOH  can be inserted an calculated.
Crystal water  CaCl2*5H2O
Neg. charged ions such as SO4-2 or SO4--  
Pos. charged ions such as Fe+3 or Fe+++   
Comunds containing isotopes H[2]2O  or D2O  (Heavy water) or enriched compunds such as C[13]H[2]4
Calculation of statistics such as:
-Moles of different elements or isotopes in a compund.
-Mass of each element in a compund
-Mass% of each element in a compund.
