v/v % = [ (volume of solute)/ (volume of solution)] x 100%. Note that volume percent is relative to the volume of the solution, not the volume of solvent. For example, wine is about 12% v/v ethanol. This means there is 12 ml ethanol for every 100 ml of wine.

We can express concentration in different ways like concentration by percent or by moles. 1) Concentration by Percent: It is the amount of solute dissolves in 100 g solvent. If concentration of solution is 20 %, we understand that there are 20 g solute in 100 g solution. concentration of substance in mol/l (g/l) • For conversion from mass to molarity divide the mass (g or g/l) with molar mass (relative AW/MW/FW) • For conversion from molarity to mass multiply the molarity (mol or mol/l) with molar mass (relative AW/MW/FW) Concentration of a solution in % % weight per weight (w/w): grams of substance In chemistry, concentration of a solution is often measured in molarity (M), which is the number of moles of solute per liter of solution. This molar concentration (c i) is calculated by dividing the moles of solute (n i ) by the total volume (V) of the: [latex]\text{c}_\text{i}=\frac{\text{n}_\text{i}}{\text{V}}[/latex] Our common acids and bases concentration reference chart allows you to easily prepare chemicals in a 1 Normal solution.

More Ways to Calculate and Express Concentration . There are other easy ways to express the concentration of a chemical solution. Parts per million and parts per billion are used primarily for extremely dilute solutions. g/L = grams per liter = mass of solute / volume of solution F = formality = formula weight units per liter of solution v/v % = [ (volume of solute)/ (volume of solution)] x 100%.
