Select Common Analytical Reagent

Compound Name

Molecular Weight (g/mol)

Target Concentration

Final Desired Volume

Formula: Mass (g) = M × V (L) × MW

Required Weight Analytical Balance

2.0000 g

(= 2,000.00 mg)

Standard Lab Preparation SOP:

Weigh exactly 2.0000 g of Sodium Hydroxide (NaOH). Dissolve in approx. 400 ml of distilled water in a beaker with stirring. Transfer quantitatively to a 500 ml volumetric flask and dilute to the graduation mark with distilled water.

Formula: C₁ × V₁ = C₂ × V₂ (Units for C₁ and C₂ must be identical).

Volume Unit

Required Stock: V₁ = (C₂ × V₂) / C₁

Pipette Volume (V₁) 1:10 Dilution

25.00 ml

+ 225.00 ml Diluent (Water/Buffer)

Dilution Step Protocol:

Measure exactly 25.00 ml of Stock Solution (C₁ = 10) into a clean volumetric flask. Add 225.00 ml of distilled water or specified buffer to make the final volume 250.00 ml. Invert gently to homogenize.
