Question

define molarity & give formula for it​

Answer 1

Answer:

Molarity :

Molarity (M) is defined as the number of moles of solute per liter of solution.

Molarity = Moles of solute/Liters of solution

$m \times \frac{n}{v}$

m = Molar concentration

n = Moles of solute

v = Liters of solution

Answer 2

Answer:Molarity of a given solution is defined as the total number of moles of solute per litre of solution. The molality of a solution is dependent on the changes in physical properties of the system such as pressure and temperature as unlike mass, the volume of the system changes with the change in physical conditions of the system. Molarity is represented by M, which is termed as molar. One molar is the molarity of a solution where one gram of solute is dissolved in a litre of solution. As we know, in a solution, the solvent and solute blend to form a solution, hence, the total volume of the solution is taken.

Explanation:The equation for calculating molarity is the ratio of the moles of solute whose molarity is to be calculated and the volume of solvent used to dissolve the given solute.

M=nV

Here,

M is the molality of the solution that is to be calculated

n is the number of moles of the solute

V is the volume of solution given in terms of litres
