Study Set Content:
V
Volume
is the ratio of a material's density with that of water at 4 °C
Specific gravity
where is water most dense
4 °C
It is therefore a relative quantity with no units.
Specific gravity
Sp. Gr
\= weight of the substance/ weight of an equal volume of water
Mole Fraction Symbol :
X
lower-case Greek letter chi
X
It is the ratio of the number of moles of solute and the total number of moles of solute and solvent.
Mole Fraction
Mole Fraction unit
No unit
ratio strength 3. percentage
a. w/w b. w/v c. v/v
Parts per million symbol
ppm
: It is defined as the parts of a component per million parts (106) of the solution. It
parts per million (ppm)
. It is widely used when a solute is present in trace quantities.
parts per million (ppm)
Molarity Symbol
M
number of moles of solute per liter of solution
Molarity
Unit: of molarity
mol/litre
represented as the number of moles of solute present per kg of solvent
Molality
Unit of molality
mol/kg
Why m is not affected by change in temperature?
Since it is dependent on mass of solute and mass do not change to small shift in temperature due to close packing of solid atoms therefore it is independent of temperature chang
: It is defined as the gram equivalent weight per liter of solution
Normality
