Dilution Calculator PPM PPB Percentage Concentration: Volume: Stock Solution: × = Dilute Solution: × Dilution refers to make a lower concentration solution from higher concentrations. Solutions usually are stored in a higher concentration, for convience of use and avoiding contamination. The dilution fomula is: Concentration (stock) × Volume (stock) = Concentration (dilute) × Volume (dilute) Dilution Calculator of Mass Percentage Concentration Solution: This calculation can be used for dilutions of solutions with concentration in Mass Percentage units, e.g. Mg/ml, ug/ml. For dilution of molar concentration solution, like mol/L, mM, nM, please use the Dilution Calculator of Molar concentration. The diluted NaCl solution is 300, with concentration 40, how much 5 NaCl stock solution is needed?
Answer: Volume (stock) = 300ml. 40ng/ml / 5ug/ml = 2.4ml Dilution Calculator of molar concentration: This calculation can be used for dilutions with molar concentration, e.g. Mol/L, nmol/L., click for molar mass calculation of chemicals. Note: 1M is equal to 1mol/L. (1) The diluted HCl solution is 300ml, with concentration 100mM, how much 5M HCl stock solution is needed?
Ten-fold serial dilutions. A ten-fold dilution reduces the concentration of a solution or a suspension of virus by a factor of ten that is to one-tenth.

Answer: Volume (stock) = 300ml. 100mM / 5M = 6ml (2)The stock HCl solution concentration is 5mol/L, 2ml of which was used to produce a diluted solution of 500ml, what's the concentration of the diluted solution? Answer: Concentration (dilute) = 5mol/L. 2ml / (500ml) = 0.02mol/L Serial Dilution Calculator: This calculation is useful when make a solution of lower concentration from its higher concentration solution while the solution units of the stock and dilute are the same, e.g. Both in copies/mL, mg/L. For example, question can be: To get 100 ml 1 × 10 5 diluted solution, how much 1 × 10 7 solution is needed? Answer: Volume (stock) = 100ml.
