This android app is a simple easy to use calculator for determiningmolecular weight of compounds. Simply enter the chemical formula ofa compound (e.g H2SO4) and the molecular weight is instantlycalculated. This app is also available online athttp://calistry.org/molecular-Weight-Calculate This app is producedby Calistry. Visit calistry.org to use hundreds of similar tools inthe field of chemistry.

Use this calculator for preparing a solutionofsolid solute. To use the calculator , first enter the formula ofthesolute. Then enter any of the three of the fourparameters,namely:N=Normality of the Solution ;Wsolute = Weight of the Solute ;V = Volume of the solution;n = Equivalence Factor (basicity of an acid or acidity of a baseornumber electron transfer in a reaction)Description :Normality of a solution is defined as the number of gramequivalentof a solute present per liter of a solution. The gramequivalent isthe ratio of molecular weight and equivalence factor.Thisequivalence factor can be thought as the number of replaceableH+ions in a molecule of an acidic solute or the number ofreplaceableOH- ions present in a molecule of a basic solute. Thusequivalencefactor of NaOH is 1 and 2 for H2SO4. In the case ofredox reactionsthis equivalence factor is the number of electrontaken or givenout of that compound in a redox reaction.This calculator is the android version of the followingwebapplication.

This is the most powerful chemicalequationbalancer. Apart from solving simple chemical equations (e.gCa(OH)2+Na2CO3 => CaCO3 + NaCl ) this can also handlechemicalequations that are combinations of multiple independentequations (eg C + H => C2H6 + CH4 + C4H10 is a combination ofthreeindependent reactions ).In short this is the most powerful chemical equationbalancer.Visit the live web version at:http://calistry.org/calculate/balanceChemicalEquation
