Proust's law or law of constant composition said that a given chemical compound always contains its component elements in fixed ratio and does not depend on method of preparation.
Water (H₂O) is made of two hydrogen atoms and one oxygen atom:
m(H) : m(O) = 2·1 : 16 = 1: 8.
Dalton said that matter is composed of atoms and atoms of different elements can join to form chemical compound.

Hope this helps!
Answer:

Explanation:
moles of Na = m/M ; Where M - molar mass of Na which is 23
moles of Na = 73/23 =3.17mol
but from the eqn n(Na) : n(NaOH) = 2:2 = 1:1
: . moles of NaOH is also 3.17mol
