Density |\left( \rho \right)| | |\rho = \displaystyle \frac {{m}}{{V}}| | Density is the ratio between the mass and volume of an object. |\rho|: density |\text {(g/mL)}| |{m}|: mass |\text {(g)}| |{V}|: volume |\text {(mL)}| |
| Concentration in g/L |\left( {C} \right)| | |{C} = \displaystyle \frac {{m}}{{V}}| | Concentration is the ratio between the amount of solute and the volume of solution. |{C}| : concentration |\text {(g/L)}| |{m}| : amount of solute |\text {(g)}| |{V}| : volume of solution |\text {(L)}| |
| Concentration and volume before and after dilution | | {C} _{1}\cdot{V} _{1} = {C} _{2}\cdot {V} _{2}| | The product of the initial volume |({V}_1)| and the initial concentration |({C}_1)| is equal to the product of the final volume |({V}_2)| and the final concentration |({C}_2)|. It is important to use the same units of volume and concentration for the initial and final situations. |{C}_1|: initial concentration |{V}_1|: initial volume |{C}_2|: final concentration |{V}_2|: final volume |
