Answer:mass of a compound required to prepare a solution of known volume and concentration

volume of solution required to dissolve a compound of known mass to a desired concentration

concentration of a solution resulting from a known mass of compound in a specific volume

Mass

37.294

=

Concentration

311.4256

x

Volume

350

x

M. Wt*

342.15

g/mol

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / CoA (available online).

The molarity calculator equation

The Tocris molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)

An example of a molarity calculation using the Tocris molarity calculator

What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?

Enter 197.13 into the Molecular Weight (MW) box

Enter 10 into the Concentration box and select the correct unit (millimolar)

Enter 10 into the Volume box and select the correct
