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
