Now let's see how to make 1 N and 1M H2SO4 from 98% concentrated H2SO4 . This calculation varies with concentration of H2SO4. Because density varies with concentration of H2SO4 . Now we are having density 1.84 for 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then first find out density of it then put that value in below formula instead of 1.84 H2SO4 is liquid, so at first we need to convert H2SO4 molecular weight (gm) into volume (ml) let's use formula density = mass / volume volume = mass of HCl / density 98.08 / 1.84 V = 53.30 ml Here we are making 1M and 1N H2SO4 from 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then use that percentage value in below formula rather than 98%. Let's use formula 1M H2SO4 (98%) = 53.30 ml [ V ] 100% ...
1) Human brain surface contain 100 billions neuromuscular cell's.
2) left side of human brain contain 1860 lakh more neuromuscular cell's than right side.
3) human brain can stay alive without oxygen up to 4-5 minutes. After that brain cells will die.
4) average weight of human brain is up to 1400- 1500 gm. but weight of Albert einstein's brain was just 1230 gm.
5) per minute 750 - 1000 ml blood get flow from our brain.
6) different type of caves which present in our brain called ventricles. (Hollow part)
7) right side of human brain control left side of body and left side of brain control right side of body.
8) left side of human brain control our conversations skills, writing and imaginations.
9) right side of our human brain control our art abalitys.

Classification of human brain.
1) cerebrum:
Cerebrum contain 2/3 part of brain.
Classifications of cerebrum:
Frontal lobe:
frontal contain motive sector's that control our speaking and wanted movements of body.
Parietal lobe:
periental contain sensatory sector's .and they are responsible for feelings like heat ,cold, light, pressure and touch.
temporal lobe:
this part of cerebrum responsible for hearing.
occipital lobe:
this part of cerebrum is responsible for seeing (visuality)
Work of cerebrum:
1) controle our wanted movements.
2) concentration.
3) memory.
4) decision power.
2) cerebellum:
This is the small part of brain.
And its surface is shallow and erosions type.
Work of cerebellum:
1) it gives balance to our body during walk.
2) cerebrum brings improvements in our wanted movements.
3) medulla oblongata:
Classifications of medulla oblongata:
1) midbrain
2) pons
3) medulla
Work: it control
1) hard beats
2) cought
3) flow of blood
4) respiration
5) sneezing
6) production of saliva
Spinal cord:
It is the part middle neuromuscular system. It is situated in back bone .
Work :
they passes impulses from skin to brain and then from brain to muscle and glands.
Medulla:
Medulla work as joint between spinal cord and pons.
