FAQ
What is %w/v?
%w/v (weight per volume) is grams of solute per 100 mL of solution. A 10 %w/v solution contains 10 g of solute per 100 mL.
What is %v/v?
%v/v (volume per volume) is mL of solute per 100 mL of solution. Use it when the solute is a liquid (e.g. 70 %v/v ethanol).
When should I use w/v vs v/v?
Use w/v for solid solutes (salts, buffers, sugars). Use v/v for liquid solutes (alcohols, acids, organic solvents).
