FORMULA'S USED IN SOLVING NUMERICAL PROBLEMS BASED ON VOLUMETRIC ANALYSIS:-

1.) Strength of solution ---~ Amount of substance in g/ litre.

2.) Strength of solution ---~ Amount of substance in g moles / litre.

3.) No. of moles ---~ Wt. in gm / mol. Wt.

---~ Volume in litres/ 22.4 at NTP

(only for gases)

4.) Molarity ---~Moles of solute / Volume in litres.

5.) No. of millimoles ---~ Wt. in gm × 1000 mol/Wt.

---~ Molarity × Volume in ml

6.) Strength of solution ---~ Normality of EQ. Wt. of the solute.

7.) No. of equivalents ---~ Wt. in gm / EQ. Wt.

8.) No. of Milli equivalents (m.eq.) ---~ Wt. in gm × 1000 Eq. Wt.

9.) Normality ---~ Strength in gm/ litre / Eq. Wt.

10.) Normality Formula ---~ N1V1 = N2V2

11.) % by weight ---~ Wt. of solvent × 100/ weight of solution.

12.) % by Volume ---~ Wt. of solvent × 100 / Volume of solution.

13.) % by strength ---~ Volume of solvent × 100 / Volume of solution.

14.) Formality ---~ Wt. of ionic solute / formula Wt. of solute × V.
