Examples for solution preparation:

1.Calculate the weight of MgCl2.6H2O needed to prepare 200ml of 1M MgCl2 solution.
 Concentration specified on the left :  Choose molarity from concentration list,  then enter 1 in the concentration of solution field, enter 0.2 in The amount of solution field;
Concentration specified on the right :Choose mass-volume percentage from  concentration list;
Pre-input parameter: Enter MgCl2.6H2O in solved formula field, click the "Calculate" button on the right of solved formula field to get the molar mass of MgCl2.6H2O;
Click the "Calculate" button at the bottom of this box, then 40.65996 gram in the amount of solute field on the right is the weigh of MgCl2.6H2O  needed.

2.How can I prepare 200ml of 75% v/v ethanol from 95% v/v ethanol?
 
Concentration specified on the left:  Choose mass-volume percentage from concentration list, then enter 75 in the concentration of solution field, enter 0.2 in The amount of solution field;
 
Concentration specified on the right: Choose mass-volume percentage from concentration list, then click checkbox to change in the concentration of solution, enter 75 in the concentration of solution field;
Click the "Calculate" button at the bottom of this box, then 0.157894737
L in the amount of solution field on the right is the volume of 95% v/v ethanol needed.

How can I prepare 1.0103mL of 0.1mol/L HCl from 37% w/w HCl? The density of 37% w/w HCl is 1.19g/mL.
 1) The first step is to convert the 37% w/w HCl to molarity(see example above), that is 12.07595mol/L;
 2) Choose molarity from concentration list on the left , then enter 0.1 in the concentration of solution field, enter 1 in the amount of solution field,click checkbox on tne right to change in the concentration of solution;
Click the "Calculate" button at the bottom of this box, then 0.008280922L in the amount of solution field on the right  is the volume of 37% w/w HCl needed.
