How do you dilute 4mg mL to 2mg mL?
Take 1 mL (4 mg) of the 4 mg/mL solution and mix with 1 mL of NS to obtain a final concentration of 2 mg/mL. Take 1 mL (5 mg) of the 5 mg/mL solution and mix with 9 mL of NS or D5W to obtain a final concentration of 0.5 mg/mL or 5 mg/10 mL.
What is molar dilution?
Molarity is a way of quantifying the concentration of a solution. Dilution is a way of decreasing the concentration of a solution. Both molarity and dilution are essential concepts for correctly performing chemical experiments in a laboratory. Let’s say that we have two glasses of water.
How do you dilute a 1 molar solution?
The simplest way is to dilute the 1M solution, which we do by adding more water to it. Vi = Vf * Mf /Mi = 0.100 [L] * 0.3 [mol/L] / 1[mol/L] = 0.03 [L] = 30 mL of the 1M solution. So, start with 30 ml of the 1 M solution and add water until you have exactly 100 ml of the diluted solution.
How do you dilute 25X to 1X?
Product(s) not sterile. Refer to Procedure. To make a 1X PBS solution dilute concentrate 25X with distilled water.
How do I make a 5mg ml solution?
All Answers (7) Somayeh, Dissolve 5 gram in 1000 ml : 5 mg /ml, Then 0.5 gram in 1000 ml : 0.5 mg /ml. in order to prepare the various concentration you must first prepare a stock solution of your plant extract. prepare the the stock by dissolving 0.5 gm in solvent.
How do you convert mg to molarity?
FROM (mg/ml) TO molarity (M): Divide the concentration (mg/ml) by the molecular weight. We will use the example of a typical immunotoxin that has a molecular weight of 210,000 grams per mole (or mg/mmole or kDa) (the molecular weight is usually found on the data sheet) and a common concentration is 1.0 mg/ml.
How do you do a 3x dilution?
Answer: Since you know the initial concentration (12x), the final concentration (3x), and the final volume (200 ml), you can use the formula: (initial concentration)(initial volume) = (final concentration)(final volume) (12x)(X ml) = (3x)(200 ml)
How do you dilute a 1 M solution to 0.1 M?
Take 1 part of your stock solution and add 9 parts of solvent (usually water but sometimes alcohol or other organic solvent). In all cases you are diluting by the same factor. The concentration of the resulting solution is 1M /10 = 0.1M where 10 is the dilution factor.
