9/100 = 12 / (100 +x) so 0.09 (100+x) = 12 so 9 +0.09x =12
therefore 0.09x = 12-9 and thus x = 3/0.09 = 33.334
So to 100g of 12% peroxide would need to add 33.34 g water.
To put another way to every 3 parts peroxide add 1 part water.
Ratio of 3:1 peroxide:water
no.
Possibly, by low pressure distillation, but it is not easy.
To dilute trypsin 10x, you can combine 1 part of the 10x concentrated trypsin solution with 9 parts of a suitable diluent, such as PBS or cell culture media. For example, add 1 mL of the 10x trypsin to 9 mL of the diluent to obtain a 1x trypsin solution. Mix thoroughly before use.
12 amp is stronger than 9 amp by 12/9
12 pounds and 9 ounces is 201 ounces.
no.
The difference between 6%, 9%, and 12% Hydrogen Peroxide solution is the Hydrogen content.
Possibly, by low pressure distillation, but it is not easy.
it will become 9 percent hydrogen peroxide and it should be okay to dye your hair with. it might look orangish at first but will turn blond like eminem. it might be really strong do not get that in your eyes.
9/12 as a percent is 75%
9/12 x 100 = 75 percent.
It is: 9/12 = 75%
Since 9 out of 12 equals 75 percent, then 9 inches out of 12 inches (a foot) is 75 percent.
It is: 9/12 times 100 = 75%
To make a 9 percent saline solution, start by preparing a 100 percent salt solution. With a bottle of 100 percent salt water, take 9 percent and dilute with distilled water to make a 9 percent saline solution.
9/12 = 0.75 = 75%
Decreasing from 12 to 9 is a 25% decrease.
