Chemical Solution Simple helps in preparation of chemical solution by dissolution of solid solute or by dilution of existing solution and in finding of moles, Molar masses, required weights of solutes and volumes of starting solutions. Supported concentration units are Molar (M), mM, uM, g/l, mg/l. Touch the units field to change the units in the aformentioned order. The app includes Molar Mass Analyser. Tap on arrow in the Mw field initiates analysis of chemical formula in the component field and set the value to Mw field. No charge values should be used. Valid examples: Mg(HCO3)2, CaCl2.2H2O, CaCl2*2H2O, (NH4)2Fe(SO4)2.6H2O, Mg(H2PO4)2, C6H12O6. Analyser is case sensitive. Application assigns dot as a decimal separator.
