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% ...
Light travell distance because our surroundings weather is the composition of atoms .that atoms are responsible for travelling of light. The distance traveled by light is directly proportional to intensity of light.
LET'S SEE HOW ATOMS ARE RESPONSIBLE FOR THAT
When you turn on torch ,it emits some radiation called photons. Atoms absorb that radiations and get excited. Means electrons which they contain, goes low energy level to high energy level. This happens with lot of atoms at a single time. Then all electrons comes to there original position,by loosing that energy. That lossed energy atomatically get pass to other atoms. That process occurre continuously. After some distance that light becomes disappear ,because light source which we are using has limited energy. That is how light Travel.
When you turn on the torch in your room ,it would be sufficient .because your room has limited area. but when you turn on torch in open Area ,you can see just limited area .you can't cover larger area with torch, because it has limited energy.

But in case of sun ,it's totally different. Because sun is the infinite source of light .sun is 151.99 million km away from earth .eventhough its light easily reaches on earth.
