ways of expressing concentration of solution

parts per million

commonly use unit of concentration for small values formula :ppm (parts per million)the top numbers of parts of component and the lower part is total parts in solution

mole fraction

define to be equal to the number of moles of a component the is divided by the total number of moles in solution formula:x(mole fraction)to the top is number of moles of component and the lower part is the total amount of moles

unsaturated

in solution in which more solute will dissolve in solution

Saturated

in solution which is no more solute is being dissolved

mass by volume percentage

is measured the mass or weight of the solute on solution formula :w/V(mass by volume percentage )the top is mass of solute and to lower part is 100ml solution

molality

the concentration of a solution expressed in moles of solute per kilogram of solvent formula:moles if solute to top but in lower part is mass of solvent in kg

qualitative expressions of concentration

*dilute * concentrated

semi quantitive expressions of concentration

* unsaturated * saturated

mass /weight percentage

it's calculated as the mass of component divided by the total mass of the mixture, times 100 percent formula : w/w(mass percentage )in the top is the a mass and in the lower part is the total amount of mass and multiplied by 100

concentrated

large amount of solute

dilute

small amount of solute in solvent

Molarity

the number of moles of solute per liter of solution formula :M(Molarity) to the top moles of solute volume of solution in litre us from lower part

volume percentage

this percentage is a measure of a concentration of substance in solution formula :V/V(volune percentage )in top is the volume of component and lower us the total volume of the solution
