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% ...
When we see the sun in midday it looks yellow but at the sunset it looks red. do you know why. If you wants know that, you must know range of visible region . Why sun looks yellow in midday ? Sun looks yellow in midday because, blue, violet colours have low wavelength but high frequencies , because of that, they scatter in all direction and sky looks blue . That means we just have to consider remained yellow, orange and red colours . This three colours have low frequencies but high wavelengths, as compare to blue and violet colour . that is why they easily reach to earth surface. There are three colours eventhough sun looks yellow because if we compare just these three colours, then we can understand orange and red colours have high wavelengths and low frequencies. But yello...
