Which proportionality applies to avogadro’s law?

Avogadro's Law states that the volume of any gas is proportional to the number of mole molecules of the gas. Calling, n the number of moles of molecules of the gas, the proportionality equation is: V is proportional to n => V = K*n. The proportionality constant depends on the temperature and pressure. K = (RT / P) => V = (RT/P) * n, So, Avogadro's law states that at constant pressure and temperature, the volume of a gas is directly proportional to the number of moles of molecules of the gas.

Explanation:

The molecular mass is the sum of the relative atomic masses of all the atoms in the molecule.

The relative atomic mass of reactants and products are calculated as follows;

Benzoic acid is C7H6O2 hence the molar mass of benzoic acid is ;

7(12) + 6(1) + 2(16) = 84 + 6 + 32 = 122.0 g/mol

Methyl benzoate is C8H8O2

8(12) + 8(1) + 2(16) = 96 + 8 + 32 = 136.0 g/mol
