Find the required volume of a stock solution to prepare a working solution. Calculate how to dilute a stock solution of known concentration.

Enter molar mass: g/mol

(equivalent to molecular weight - **M. W.** or formula weight - **F. W.**)

In the following boxes, always fill all but one field and click 'Calculate'. Don't use commas to separate thousands.
