\(concentration~in~g~dm^{-3}=\frac{mass~of~solute~in~g}{volume~in~dm^{3}}\) 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 ...

0.5 mol of sodium hydroxide is dissolved in 2 dm 3 of water. Calculate the concentration of the sodium hydroxide solution formed. Concentration in mol dm-3 = \(\frac{\textup{amount~of~solute~in~mol}}{ ...
