Question

# Pls provide me with the various equations of molality,normality,molarity,formality and it's application with definition

Solution

## 1: Molality a) is defined as the “total moles of a solute contained in a kilogram of a solvent.” The term needs to calculate the mass of the solvent and moles of solute b)Molality, m=                    ( moles of solute/Kg of solvent) c)aplications     *as a measure of concentration is that           molality only depends on the masses of solute and solvent      *solutions prepared volumetrically 2:Molarity(M) a)  is the concentration of a solution expressed as the number of moles of solute per liter of solution b)equation is      (moles of solution/liters of solution) c) aplications *Molarity can be used to calculate the volume of solvent or the amount of solute. *The relationship between two solutions with the same amount of moles of solute can be represented by the formula c1V1 = c2V2, where c is concentration and V is volume 3:Normality(N) a)   Normality is a rarely used expression which indicates the concentration of a solution. It is defined as the gram equivalent weight per liter of solution. b)equation (gram equalent weight/liter of solution) c)aplication   *Normality is used to express hydroxide ion’s or hydronium ion’s  concentration of solution in acid-base chemistry. *Used in precipitation reactions to measure the number of ions. *In redox reaction, it describes the number of electrons that an reducing agent or oxidizing agent can donate or accept 4:Formality(F)   a) is the number of gram formula masses of the ionic solute dissolved per litre of the solution. b)equation    (no of gram formula mass/volume of solution in liter) c)    * used in calculations related to ionic compounds
