The concentration of a solution is the amount of solute dissolved in a certain volume of solution. This concentration is usually expressed in molarity, which is the moles of solute per liter of solution.
INSTRUCTIONS
1. Select a solute to be used by typing the formula into the text box.
- Enter the formula making sure to use correct capitalization.
Subscripts are not supported.
- The program collects like elements from different parts of the
formula, thus C2H6O and CH3CH2OH will give the same results.
- Chemical groups that are normally written in parentheses should
be typed in with parentheses. Brackets are not required for multiple
sets of parentheses. The calculations will handle two levels of
parentheses: for example, the molecular weight of Ni(N(CH3)3)4Cl2
will be calculated properly.
- Waters of hydration or solvents of solvation should be written in
parenthetical notation. For example, CuSO4 *5H2O should be entered as
CuSO4(H20)5.
2. Vary the scrollbar to select the number of grams of solute to be used.
3. Enter the volume of solution into the text box on the right of the screene.
4. Click on the calculate button to determine the molarity of the solution. Molarity is in units of moles per liter.
