Mendeleev · Tool
Solution Preparation Calculator
Choose a solute formula, target molar concentration and final volume. The calculator gives the amount of substance and the corresponding solute mass.

Example
250 mL of 0.100 M NaCl
0.100 mol/L × 0.250 L = 0.0250 mol NaCl. With a molar mass of about 58.44 g/mol, the calculated solute mass is 1.461 g NaCl.
What the number represents
The result is the calculated mass of the chemical formula entered. In a real laboratory, purity and hydration state can change the mass that must actually be weighed. Follow the preparation method required for the material and the accuracy needed.
The requested volume is the final solution volume, not simply the amount of solvent to pour in. For concentration calculations, those two volumes should not be treated as interchangeable.
