What does it means by 100 times dilution of stock dilution?
A 100 times dilution of a stock solution means that you are adding 1 part of the stock solution to 99 parts of a diluent (such as water) to make a total volume of 100 parts. This results in a final solution that is 1/100th the concentration of the original stock solution.
How do you make 600 mL of a 1 molar solution of HCl using a 6 molar stock solution?
To prepare 600 mL of 1 M HCl solution from a 6 M stock solution, you can use the formula: M1V1 = M2V2, where M1 = concentration of stock solution, V1 = volume of stock solution needed, M2 = final concentration, and V2 = final volume. Plugging in the values: 6 M x V1 = 1 M x 600 mL. Therefore, V1 = 100 mL. Therefore, you would need to measure 100 mL of the 6 M stock solution and dilute it to 600 mL with water to make a 1 M HCl solution.
How do you prepare 100 mM phosphoric acid?
To prepare 100 mM phosphoric acid solution, you can dilute a more concentrated phosphoric acid stock solution to the desired concentration by adding the appropriate volume of water.

How do I make ml of 5 percent bleach solution from a 8.25 percent solution?
To make a 5% bleach solution from an 8.25% solution, you can use the dilution formula (C_1V_1 = C_2V_2), where (C_1) is the concentration of the stock solution (8.25%), (V_1) is the volume of the stock solution you need, (C_2) is the desired concentration (5%), and (V_2) is the final volume of the diluted solution. For example, to make 100 ml of a 5% solution, you would calculate (V_1 = \frac{C_2 \times V_2}{C_1} = \frac{5 \times 100}{8.25} \approx 60.61) ml of the 8.25% solution. Then, add enough water to reach a total volume of 100 ml.

Preparation of 100ml 0.5N from a stoke solution of 5.0N HCL?
To prepare 100ml of 0.5N HCl solution from a stock solution of 5.0N HCl, you need to dilute the stock solution with water. To calculate the volume of stock solution needed, you can use the formula C1V1 = C2V2, where C1 is the concentration of the stock solution, V1 is the volume of the stock solution needed, C2 is the desired concentration, and V2 is the final volume of the diluted solution. So, V1 = (C2 * V2) / C1 = (0.5 * 100) / 5 = 10ml of the stock solution. Dilute this 10ml of stock solution to 100ml with water.

Plugging in the values, you would calculate V1 to be 20 ml. Therefore, you would mix 20 ml of the 2 M stock solution with water to make a total volume of 100 ml to get a final concentration of 0.4 M magnesium sulfate.
How many litres of 12 percent sodium hypochlorite solution are needed to make 100 Litre of 2 percent sodium hypochlorite solution?
To make a 2% sodium hypochlorite solution from a 12% solution, you can set up the equation: 12% solution * x litres = 2% solution * 100 litres Solving for x, you get: x = (2% solution * 100 litres) / 12% = 16.67 litres Therefore, you would need 16.67 litres of the 12% sodium hypochlorite solution to make 100 litres of a 2% solution.
