Consider the formation of water molecule. Hydrogen combines with oxygen to form a water molecule.
In this case, the total mass of the reactants = total mass of the products. Also, the number of atoms of hydrogen and oxygen in the reactants side and the products side are equal.
that's all I know
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
Answer:
T = 11.4°C
Explanation:
Given that:
weight of solute w (glucose) = 12 g
weight of solvent W (acetic acid) = 50 g
Molar depression constant of solvent (Kf)= 3.90°C/m
Temperature of solvent freezing point T₀ = 16.6°C
Temperature of solution freezing point Tₓ = (T₀ -T) = ???
Molar mass of solute (glucose) = 180.2 g/mol
Using the expression;
(T₀ -T) = 
-T = -16.6 °C + 5.2 °C
- T = -11.4°C
T = 11.4°C
∴ The freezing point of the solution is said to be = 11.4°C
