Description

Solution Mol calculator is a calculation sheet that solves chemical solution calculation especially solution blending problems. Solution Mol calculator Lite is a Lite version of the Solution Mol calculator. This can operate the P button up to 3 times. When 10 minutes pass and it is resumed, the P button can be used again. This software solves the problem not as a black box but as a white box. You need to think the process of solving a problem. A typical problem is as follows. (Example) There is concentrated ammonia (NH3) water. This weight concentration is 28% and density is 0.90 g/cm3. I would like to make ammonia 0.1 molar solution 250 mL by diluting the concentrated ammonia water with pure water. How much liters is the starting concentrated ammonia water? Solution Mol calculator solves the problem in the following three steps. //Step 0: Preparation// Prepare atomic (molecular) weight. This is as follows. Molecular weight of NH3 = 17 [g/mol] //Step 1: Definition// Enter known data into the SMol sheet. Rows correspond to solutions. The fifth row is a special row that corresponds to the total blended solution. Columns correspond to the attribute data of the solution. First row Name = 28%NH3, Aw = 17, WgtC = 28, Dty = 0.90 Second row Name = Water Fifth row Name = 0.1molNH3, Aw = 17, MolC = 0.1, SolVol = 250 //Step 2: Calculation// Attribute data are not independent but mutually related by formulae. Calculation is a conversion from unknown data to known data using the formulae. The formulae are embedded in P, G, and V buttons. Touching out those buttons executes the formulae and changes unknown data to known data. Touch out buttons as follows. Set calculation mode to MolC. In this mode, P button calculation is executed by referencing MolC. Touch out P_SolMol button of the fifth row. W data of the fifth row is changed to known data. Touch out V_W button of the first row. W data of the first row is changed to known data. Set calculation mode to WgtC. In this mode, P button calculation is executed by referencing WgtC. Touch out P_W button of the first row. SolVol data of the first row are changed to known data. It turns out that the volume of the starting concentrated ammonia water is 1.69 mL. [Data label] Name: Solution name (option). Aw [g/mol]: Atomic or molecular weight of solute. MolC [mol/mL]: Mol volume concentration of solution. WgtC [%]: Percent weight concentration of solution. Dty [g/mL]: Solution density. SolVol [mL]: Solution volume. SolWgt [g]: Solution weight. n [mol]: Mol quantity of solute. W [g]: Weight of solute. StdVol [L]: Gas volume of solute at 0 degC and 1 atm. [Calculation mode] P button calculation is executed by referencing either WgtC or MolC. This mode is set by selection of MolC or WgtC. G button and V button are irrelevant to this calculation mode. [Buttons and data] //P button and P data group// P (put) button inputs data to which the P button is assigned. P data group is a group of data to which the P buttons are assigned. The P data group has a special character. When one P data is input, all other data of the P data group are updated by formulae. //G button// G (get) button gets data from other data using formulae. //V button// V (vertically get) button gets data from other row data using the formulae. The calculation is executed among rows. //C button// C (Clear) button clears all row data. [Color change] Color change shows what data are input, output, or referenced data in the button execution. Input data:Blue color Referenced data:Yellow color Output data:Green color Uncalculated data:Red color [Formulae] Embedded formulae are as follows. MolC = 1000 x n / SolVol WgtC = 100 x W /SolWgt Dty = W /SolWgt n = W/Aw StdVol = 22.414 x n SolWgt(5) = SolWgt(1) + SolWgt(2) + SolWgt(3) + SolWgt(4) n(5) = n(1) + n(2) + n(3) + n(4) W(5) = W(1) + W(2) + W(3) + W(4)
