Solutions are formed when solutes dissolve in solvents. If the number of moles of solute and the volume of solvent used is known, the concentration of the solution can be calculated. The concentration ...

\(concentration~in~g~dm^{-3}=\frac{mass~of~solute~in~g}{volume~in~dm^{3}}\) The units for concentration are also shown as g/dm 3, but this means the same as g dm-3. 8 g of sodium hydroxide is ...
