yes you need concentration especially in school. if you are getting annoyed and need some concentration ask to go out in to the hall.
I need an example for concentration
About 13M. You can assume it is 13M if you don't need an exact concentration (like if you need a ~1M HCl solution for an extraction or whatever) but if you need an exact concentration (for a titration, for example) then you will need to standardize your HCl first.
You need a graphic concentration versus absorbance.
That depends on which micro organisms. Some need a very small concentration to be dangerous to human, others need a large concentration. Still others are not harmful to humans in any concentration.
To determine the pH of a solution from the hydroxide ion concentration, you also need the concentration of the hydrogen ion. Once you have that information, you can use the equation pH = 14 - pOH, where pOH is calculated as -log[OH-] and [OH-] is the hydroxide ion concentration.
There were many Nazi concentration camps, so you need to provide more information.
Mol is an official unit of concentration in SI, not of mass.The transformation of a concentration expressed in mass per volume in a concentration in moles is at your choice.
Taking a hard test takes lots of concentration
To make 2 L of saturated sugar water with a concentration of 0.6 mol/L, you would need 1.2 moles of sugar in total. Since the concentration of the solution is the same as the concentration of sugar, you will need to dissolve 1.2 moles of sugar in 2 L of water.
They both need physical and mental concentration.
hi
you need a silent place and a lots of concentration
