Calculate the mass of a compound to weigh out for a specified molar concentration and final solution volume.
How it works
Method: Mass (g) = concentration (mol/L) × final volume (L) × molecular weight (g/mol).
Example: A 100 mL solution of 0.1 M glucose at 180.16 g/mol requires 1.8016 g glucose. Add solvent to the final volume.
