How to make 1N and 1M H2SO4 ?

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%    ...

HOW DID LIFE BEGIN ON THE EARTH?

     At first we must know about our solar    system. Our solar system has been situated in Milky way  which is our galaxy. There are a lot  of galaxies and they all contain numbers of   solar systems just like ours milky way. One interesting fact is that all galaxies does have their own gravitational force and that all are held together by that gravitational force.  Just like galaxies, all planets which are situated in that different galaxies also have gravitational force and that force is responsible for the movement of planet's in there particular orbits around the sun. Sun is the centre of our solar system just like centre of any atom and other planets are moving around the sun just like electrons but in our solar system single orbit contain only one planet.  That all planet's have there different gravitational force. Ther are 8 planets in our solar system which have gravity and Jupiter have more gravity than other remaining sev...

ANTIBIOTICS

  What are antibiotics ?          Antibiotics are medicines that help us to stop infection caused by bacteria.they do that by killing them or stop their reproduction.           Sir Alexander Fleming was the first person who invented first antibiotic. That antibiotic was given name penicillin.                   Born :  6 August 1881, lochfield, Scotland   Died :  11 March 1955, London,United kingdom  Nobel prize:  They got nobel price in physiology or medicine in 1945, for the invention of penicillin that work against bacteria.  Period of 1940 -1960 is known as golden age for antibiotics.  Up to the 1997 scientist made thousands antibiotics.     Type of antibiotics: 1) Broad spectrum antibiotics:                       ...
