Answer:
3: Lactone
Explanation:
Lactones are defined as carboxylic esters that contain the structure (−C(=O)−O−) which is essentially showing that an ester has now become part of the chemical structure of the ring.
Thus, looking at the question, it has the structure as defined in Lactones.
Thus, we can say that the compound is a Lactone.
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>
