The wording is important here.
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.
take 1 ml, add 9 ml water.
He urged people to use their sences to make observations, just as scientist today make observations
they use the scientific method
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
Rocket scientists make anything from $40,000 to $70,000 a year More than that.
110
2 times dilution from 100% acetone
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.
Yes
How much does a forensic scientist make in a year an if i go to college how many years would it take me to become a forensic scientist.

In chemistry and biology, the dilution factor is the total number of unit volumes in which the material is dissolved. As I understand it, the dilution refers to the dilution ratio. If you add 1 part of something to 4 parts of something else, the dilution ratio is 1 to 4. The dilution factor counts all the parts and expresses the same thing as 1 out of 5.
to make sure its correct
NO
You add 9.09ml of stock solution to a volumetric and make it up to 1 litre to get a 110 dilution
