Molarity Formula
Molarity is defined as the number of Mole of solute present in one litre or one dm3 of the solution .
Contents
Or
One milimol of the solute present in one mL of solution.
- Molarity is denoted by M.
- Unit of molarity is mol/L or Mole/dm3
- Molarity volume is temperature dependent. Molarity canchange with temperature.
Formula :
M = molarity
n = number of Mole of solute
V = Volume of solution in litre
- If the volume of solution given in mL that the formula will be following.
Question:
2.46 g of NaOH is dissolved in water and the solution is made to 100 cm3 in volumetric flask calculate the molarity of the solution?
1 L = dm3
1 mL = 1cm3
Molar mass of NaOH = 40
Formula of molarity:
