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.
3. How
can I prepare 1.0×103mL 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.
