Question

A compound consist of Na , S , H and O as per the following % composition:-
Na = 14.28 , S = 9.92 , H= 6.2
Give the molecular formula of the anhydrous compound. If all the hydrogen are present in combination with oxygen as water of crystallization , find the structure of the water of crystallization.​

Answer 1

Explanation:

Element mass % Atomic mass(g) m%/At. mass Integral ratio

Na 14.31 23 0.622 2

S 9.97 32 0.311 1

H 6.22 1 6.22 20

O 69.5 16 4.34 14

Empirical formula is therefore

empirical mass=g

Given:

Molecular mass = 322 g

molecular formula =empirical formula=

Given that all the hydrogen in the compound is reset in combination with oxygen as water of crystallisation

If water of crystallization are then,

or

Crystallized water is remaining atoms are

therefore, the molecule is
