Answer:
Explanation:
Given that:-
Mass of the hydrated salt = 7.028 g
Mass of the anhydrous salt = 3.100 g
Mass of water eliminated = Mass of the hydrated salt - Mass of the anhydrous salt = 7.028 - 3.100 g = 3.928 g
<u>Moles of water: </u>
Mass of water = 3.928 g
Molar mass of = 18 g/mol
The formula for the calculation of moles is shown below:
Thus, moles are:
<u>Moles of anhydrous salt: </u>
Amount = 3.100 g
Molar mass of = 142.04 g/mol
Thus, moles are:
The simplest ratio of the two are:
=0.02182 : 0.2212 = 1 : 10
<u>Hence, the formula for hydrate is:- </u>
