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% ...
Sound create just because of vibration of things. Sound need medium for its propagation. Sound can't propagate in vaccum. Sound can travel through all of three mediums solid, liquid, and gas. Speed of sound varies with mediums. 1) Solid 2) liquid 3) gas 1)* In case of solids, speed of sound is very fast in glass. ( Nickel =6040 m/s, steal =5960 m/s, iron =5950 m/s) 2)* In case of liquid, speed of sound very fast in sea water . ( sea water=1531m/s) 3)* I case of gas, speed of sound is very fast in hydrogen gas . ( hydrogen gas=1284 m/s) At normal temperatures speed of sound is= 340 m/s In dry air speed of sound is =332 m/s. SOUND TRAVEL IN TWO WAYS 1) Transverse wave = it create when oscillations of wave are perpendicula...
