How much stock solution do I need to dilute to 200 ppm?
By rearranging the equation, we will find the volume of stock solution required: Therefore, we need to dilute 0.005 L (or 5 mL) of stock solution to a final volume of 1 L to get a 200 ppm NaOH solution. You can check Step 1 with this ppm to molarity calculator, and check Step 2 with the solution dilution calculator!
What is the difference between ppm and molarity?
ppm = 1 mg solute per liter of solution. This last one works because the solution concentration is so low that we can assume the solution density to be 1.00 g/mL. Also, it's this last modification of ppm (the mg/L one) that allows us to go to molarity (which has units of mol/L).
How do you calculate ppm of solute?
ppm = 1 mg solute per 1 kg solution. Then, for an aqueous solution: ppm = 1 mg solute per liter of solution. This last one works because the solution concentration is so low that we can assume the solution density to be 1.00 g/mL.
What is the molarity formula for dilute solutions?
Just multiply g/L by 1000 to convert g to mg, and you have ppm (in mg/L of water). This ppm to molarity formula for dilute solutions is: ppm = moles/L * molar mass * 1000
How do you calculate molar concentration from ppm?
Take the solution's density in g/L . Divide it by the solute's molar mass in g/mol . The resulting quotient is the solution molarity in mol/L . In case you have the ppm value, repeat all the steps but substitute the density with the ppm and multiplying everything by 1000 mg/g .
How do you find the molar concentration of a stock solution?
To calculate the Molar Concentration, we will find the molar concentration by dividing the moles by liters of water used in the solution. For example, the acetic acid here is completely dissolved in 1.25 L of water. Then divide 0.1665 moles by 1.25 L to get the molar concentration, which will be 0.1332 M.
How do you calculate the molarity of final methylene blue?
Taking into account that the molar mass of methylene blue is equal to 319.8 g/mol, the molar concentration (also called amount concentration) of methylene blue in this solution is 0.5/319.8 = 0.0016 mol/L.
What is the molar mass of blue dye?
(Note the molar mass for Blue #1 = 792.84 g/mol.

How do I calculate the concentration of a solution?
The standard formula is C = m/V, where C is the concentration, m is the mass of the solute dissolved, and V is the total volume of the solution. If you have a small concentration, find the answer in parts per million (ppm) to make it easier to follow.
How do I calculate molarity?
As mass / volume = molarity * molar mass , then mass / (volume * molar mass) = molarity . Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M . You can also use this molarity calculator to find the mass concentration or molar mass.
How is methylene blue concentration measured?
The concentration of MB solution was measured by UV–Vis spectroscopy method (Rayleigh UV–Vis 1800 apparatus) using a flow cuvette (measurements were made every 20 s). The concentration of MB was determined by a wavelength of 664 nm, at which a characteristic maximum of MB occurs.
What is the concentration of methylene blue?
Standard curve of methylene blue at concentration range from 5 to 60mgL−1 at room temperature.
How do you find the concentration of a dye?
You will use the absorption of visible light to determine concentration and to identify different dyes. If the concentration of a solution is unknown, the concentration can be measured by determining the amount of light it absorbs (its absorbance, A) at a particular wavelength (λ), using a spectrophotometer.
What is the molar absorptivity of the blue dye?
To demonstrate the use of evanescent sensing for liquid concentration measurements, 400 nl droplets of aqueous solutions of FD&C Blue 1 dye (molar absorptivity = 1.38 x 10-5 M-1 cm-1) were transported across the beam path at a speed of 250 µm/s.

You have to select the proper to prepare dye solution. If you want to prepare the solution in ppm , use ethanol as a solvent in which most of the dyes are soluble.
