The chemical reaction would be expressed as follows:
HBr + LiOH = LiBr + H2O
We are given the volumes and corresponding concentration to be used for the reaction. We use these values to solve for the concentration of the other reactant. We do as follows:
0.253 mol LiOH / L solution ( 0.01673 L ) ( 1 mol HBr / 1 mol LiOH ) = 0.00423 HBr needed
Concentration of HBr =0.00423mol / .010 L = 0.423 M HBr
-well, we all need water as living organisms in order to live. water helps us clean our body (just like you clean yourself in a shower to clean your skin),but drinking water helps you to take a shower inside your body! (sounds weird but true XD) you get the point... here are a few things water does to our body:
- water helps helps our skin to look beautiful (you can say youthful skin) and even beauty itself.

- it gives us nutrients and minerals
- it helps us to maintain out blood pressure
- it also helps to regulate our body temperature
- it transfers oxygen through the whole body
- it helps with digestion

-prevents from you have a stinky breath *-*
- it helps with back-pain, headaches, heart health...etc
