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 of a solution is measured in moles per litre (mol l ...
For example, 250 ml = 250 cm 3. 100 cm 3 of dilute hydrochloric acid contains 0.5 g of dissolved hydrogen chloride. Calculate the concentration of the acid in g dm-3.
Molarity is the concentration of a solution in terms of the number of moles of the solute in 1 dm 3 (1 liter) of the solution. What are the units of molarity? The units of molarity are M or mol/L. A 1 ...
