Example: dilute concentrated NaCl-water solution in mol/L
In main menu Click Popular services>Dilute solution, then choose concentration
mol/L, temperature at 25C. It is optional to input solvent and solute information.
Adding solvent and solute information can help user keep record at next step.
Then choose method to add water solvent information from system (see figure 1) or
add my solvent (see figure 2).
Figure 1. Choose solvent water from system.

Figure 2. Add solvent water by user.
Click Dilute solution button to next step. The user can input target concentration
say 0.1 mol/L, concentrated solution concentration say 1 mol/L, and solvent
water volume,say 1000ml (see figure 3). Then click calculate button to get solvent
volume, concentrted solution volume, diluted solution volume. User may use
concentrated solution volume as input (see figure 4) or final diluted solution volume
as input (see figure 5) to calculate rest information. Currently, the system
does not consider solute effect to solution volume.
