If it is a 2 *in* 5 dilution, then the scientist would need 200 ml of concentrate. The best way would be to take a graduated cylinder, put about 200 ml of solvent into the cylinder. Then put in the 200 ml of concentrate. Then add enough additional solvent to make a total of 500 ml. Mix, then pour it into a labeled and dated bottle, and screw on the lid.
If it is a 2 *to* 5 dilution, then you need 2/7ths concentrate, and 5/7ths solvent. One seventh of 500 ml is about 71.43, so you would need 142.86 ml of concentrate, and fill the rest with solvent until the total is 500 ml.

He urged people to use their sences to make observations, just as scientist today make observations
actually almonds does not make you smarter but it helps keep you concentrate better combine almonds with more (or just) reading and study will get you smarter
they use the scientific method
Rocket scientists make anything from $40,000 to $70,000 a year More than that.
To make a 50% acetone control, you can mix equal parts of acetone and water. For example, if you start with 10 ml of acetone, you would add 10 ml of water to make a 50% acetone solution.
You would need 30 ounces of concentrate to make 30 gallons of liquid if one ounce of concentrate is needed to make one gallon.
To make a 500 dilution, add 1 part of the substance you are diluting to 499 parts of water. For example, if you have 1 mL of the substance, you would add 499 mL of water to make a total volume of 500 mL for the dilution.
To find out how many ounces of chemical it would take to make 100 gallons of finished dilution at 0.5%, we can set up a proportion. Since 11 ounces of chemical are used in 10 gallons of water, we can establish the ratio of ounces of chemical to gallons of water as 11:10. By setting up a proportion and solving for x, we find that it would take 110 ounces of chemical to make 100 gallons of finished dilution at 0.5%.
Dilution of acid does not change its chemical properties, so the acid itself is not weaker. However, dilution can reduce the concentration of the acid in a solution, making it less corrosive or less likely to cause harm upon contact.
The salary of a forensic scientist can vary depending on factors like experience, location, and employer. On average, a forensic scientist can make anywhere from $50,000 to $100,000 per year, which translates to roughly $4,000 to $8,300 per month.
If you dilute a solution of pH 5 with water, the pH would increase. However, the exact pH value after dilution would depend on the initial concentration of the solution and the extent of dilution.
to make sure its correct
Dilution is the process of reducing the concentration of a substance by adding more solvent. The dilution factor is the ratio of the final volume of the diluted solution to the initial volume of the concentrated solution. It is used to calculate the new concentration after dilution.

You add 9.09ml of stock solution to a volumetric and make it up to 1 litre to get a 110 dilution
