It was named Avagadro number for the reason that it was discovered by Amadeo Avagadro, it was named after his last name. The one who in reality initially evaluated the real number of particles in a given substance, was Josef Loschmid. Avagadro was a legal counselor who had an enthusiasm for it, and the reason the number is named after him was a direct result of a French physicist named Jean Baptiste Perrin. Perrin utilized the term as a result of Avagadro's enthusiasm for Brownian movement. What Avagadro had done was assembled everything that researchers had found to help clarify the varieties that existed amongst iotas and atoms. The mole unit is short for the German word molekulargewicht. It was to some degree an aggregate push to build up the idea. Every individual that is said to have found it, is an alternate individual, however these four individuals are the most pertinent

The specific gravity of a sample is the ratio of the density of the sample with respect to one standard sample. The standard sample used in specific gravity calculation is water whose density is 1 g/mL. The solution having specific gravity 1.30 is the density of the sample that is 1.30 g/mL. Thus the weight of the 30 mL sample is (30×1.30) = 39 g.
Now the mass of the 10 mL of water is 10 g as density of water is 10 g/mL. Thus after addition the total mass of the solution is (39 + 10) = 49g and the volume is (30 + 10) = 40 mL. Thus the density of the mixture will be 
g/mL. Thus the specific gravity of the mixed sample will be 1.225 g/mL.
