Question

Define molarity ??????????????????????????????????

Answer 1

heya dear

Molarity of a solution is the number of moles of the solute per litre of solution (or number of millimoles per ml. of solution). Unit of molarity is mol/litre or mol/dm3 For example, a molar (1M) solution of sugar means a solution containing 1 mole of sugar (i.e., 342 g or 6.02 x 1023 molecules of it) per litre of the solution.

• Molarity is most common way of representing the concentration of solution.


If molarity and volume of solution are changed from M1, V1 to M2, V2. Then,

  M1, V1 = M2, V2 (Molarity equation)

depend on temperature as, M ∝ 1/T

 

 


• When a solution is diluted (x times), its molarity also decreases (by x times)

Answer 2

Hey mate!

Here's your answer!!

✔️Molarity is defined as the number of moles of solute present per litre of the solution. Thus

✔️Molarity = Number of moles of solute / Volume of solution (in litres)

✔️Here number of moles = Mass of solute / Molar mass of solute.

✔️Solutions labeled with molal concentration are denoted with a lower case m. A 1.0 m solution contains 1 mole of solute per kilogram of solvent.​
