(x L)(6.00M) = (0.5 L)(3M)
x = 0.25 liters (250 mls)
To make a 0.5 L of 3 M HCl solution, you would need to dilute the 6.00 M stock solution by a factor of 2. You can calculate the volume needed by using the formula M1V1 = M2V2, where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume. So, you would need 0.25 L of the 6.00 M HCl stock solution to make 0.5 L of 3 M solution.
To make a 5X solution from a 10X stock, you can dilute the 10X stock solution by adding an equal volume of diluent (such as water or buffer) to the original solution. For example, if you have 1 mL of the 10X stock solution, you would add 1 mL of diluent to make a 5X solution.
To make a solution by diluting a stock solution, you add solvent (usually water) to the stock solution to decrease the concentration. The final concentration is calculated using the formula: C1V1 = C2V2, where C1 is the initial concentration, V1 is the volume of the initial solution, C2 is the final concentration, and V2 is the final volume after dilution.
To prepare 1N H2SO4 from 95% H2SO4, you would first need to dilute the 95% H2SO4 with water by adding the appropriate amount of water to achieve the desired concentration. To calculate the volume of 95% H2SO4 needed to make 1N solution, you need to use the formula: (Normality of stock solution) * (Volume of stock solution) = (Normality of diluted solution) * (Volume of diluted solution). Adjust the volumes accordingly to prepare the desired 1N solution.
To prepare a 6N NaOH solution from a 10N NaOH solution, you would dilute the 10N solution by adding water. Use the dilution formula: C1V1 = C2V2, where C1 is the initial concentration (10N), V1 is the volume of stock solution needed, C2 is the final concentration (6N), and V2 is the final volume of the solution you want to make. Calculate the volume of the 10N solution needed and add water to reach the final desired volume for a 6N NaOH solution.
To prepare 0.02M NaOH from 1M NaOH solution, you will need to dilute the 1M solution. Use the formula: C1V1 = C2V2, where C1 is the concentration of the stock solution (1M), V1 is the volume of the stock solution you will use, C2 is the desired concentration (0.02M), and V2 is the final volume of the diluted solution. Calculate the volume of 1M NaOH solution (V1) needed to make the desired 0.02M concentration and dilute it with water to reach the desired volume (V2).
To make a 5X solution from a 10X stock, you can dilute the 10X stock solution by adding an equal volume of diluent (such as water or buffer) to the original solution. For example, if you have 1 mL of the 10X stock solution, you would add 1 mL of diluent to make a 5X solution.
To make a parts per trillion (ppt) solution, you would need to add an extremely small amount of solute to a large amount of solvent. For example, if you want a 1 ppt solution, you would add 1 gram of solute to 1,000,000 grams of solvent. It is crucial to use highly accurate measuring instruments and follow strict protocols to ensure the precision required when working with such low concentrations.
The volume is 0,3 mL.
To find the volume of the 2.00 M HCl stock solution needed, we use the formula M1V1 = M2V2. Rearranging for V1 gives us V1 = (M2 * V2) / M1, where M2 is the desired concentration (0.50 M), V2 is the final volume (150 mL), and M1 is the stock concentration (2.00 M). Plugging in the values gives V1 = (0.50 M * 150 mL) / 2.00 M = 37.5 mL. You will need 37.5 mL of the 2.00 M HCl stock solution to make a 150 mL solution of 0.50 M HCl.
You need 6,9 mL stock solution.
20 volume is 6% solution. To make it 3% solution just add same volume of water to the original 6% solution and you have double volume of 3% solution.
To make a 1000 ppm solution of chloride ion, you would need to dissolve 1 gram of sodium chloride (NaCl) in 1 liter of water. This concentration corresponds to 1 mg of chloride ion per 1 kg of solution.
To make 10 volume developer from 20 volume developer, you can mix equal parts of 20 volume developer and distilled water. For example, mix 1 part of 20 volume developer with 1 part distilled water to create 10 volume developer.
1 part of stock+ 2part of dillution
To make a 5% solution of calcium chloride with a total volume of 500 ml, you would need to add 25 grams of calcium chloride. This is calculated by multiplying the volume of the solution (500 ml) by the desired concentration (5%) and converting to grams.
To prepare 6 nM ammonium hydroxide a 30 percent solution you need to know the volume of the 30 percent solution that you have and the volume of 6nM solution you would like to make. Then use the following formula: C1V1 = C2V2 where C = concentration in moles/Liter and V = volume in liters.
To make a percent sucrose solution, dissolve a specific weight of sucrose in a specific volume of water. For example, to make a 10% sucrose solution, dissolve 10 grams of sucrose in 90 mL of water. The formula to calculate the amount of sucrose needed is: (percent sucrose/100) x volume of solution = weight of sucrose (in grams).
