Answer: The answer is Parasite ma dude
Explanation:
In evolutionary ecology, parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life.

The molecular formula of hydrate : CaCl₂.6 H₂O
So there are 6 molecules of H₂O
<h3>Further explanation</h3>
Given
54.7g CaCl₂ and 53.64 g H₂O
Required
The number of molecules H₂O
Solution
mol CaCl₂ :
= mass : MW
= 54.7 : 111 g/mol
= 0.493
mol H₂O :
= 53.64 : 18 g/mol
= 2.98
mol ratio H₂O : CaCl₂ :
= 2.98/0.493 : 0.493/0.493
= 6 : 1
The mass of impure 
is 20.7167 g. The decomposition reaction is as follows:
Here, 1 mole of gives 1 mole of MgO.
Molar mass of and MgO is 84.31 g/mol and 40.3044 g/mol respectively.
Converting number of moles in terms of mass,
Here, M is molar mass.
Since, 
Thus, 
On putting the values,
Rearranging,
Or,
...... (1)
Let the mass of impurity be 
and mass of impure is 20.7167 g thus,
...... (2)
Also, mass of impure MgO is 16.8817 g thus,
...... (3)
On comparing equations (2) and (3),
Putting the value of 
in equation (1),
Or,
Or,
Or,
Or,
Thus, magnesium carbonate present in the original sample is 7.35 g.
