.
A unit of solution concentrations of solvent (solvent) solute (solute) to tell the volume ของตัวถูกละลาย contained in the solution to tell is, as the concentration of solution
how to tell concentration
Telling the solution concentration can tell how many is
1. Was divided 3 style is
11% by mass per mass or percentage by mass is the mass of solute in a solution of said existing 100 units (unit using the same mass are the same unit Such as kg), such as solution of sodium chloride (Nacl) concentration 15Mean in sodium chloride solution 100 grams A sodium chloride melt is about 15 g
12% by volume / volume or percentage volume is the volume of solution contained ในสารละลาย 100 tell the same volume units (volume units to use must be the same unit such as cubic centimeter (cm3)Or L)), such as ethanol water solution concentration by volume. 30 means in the solution is 100 DM3 ethanol soluble 30 cm3 This method is commonly used to tell a liquid solution in a liquid or gas in gas
13% by mass per volume is said mass of solute contained in the solution 100 volume units (units of mass and volume must comply Such as grams per cubic centimeter (g / cm3) kg per cubic เดติ meters (kg / dm3)20 by mass per volume) means that in aqueous solution
