An atom is the smallest particle of an element.

2) Elements have only one kind of atom.

Compound always have more than one kind of atom.

1. was the value calculated by the student.

2. was the of ethylamine value calculated by the student.

Explanation:

1.

The value of Aspirin solution = 2.62

Moles of s asprin =

Volume of the solution = 0.600 L

The initial concentration of Aspirin  = c =

initially

c       0    0

At equilibrium

(c-x)      x   x

The expression of dissociation constant :

:

was the value calculated by the student.

2.

The value of ethylamine = 11.87

The initial concentration of ethylamine = c = 0.100 M

initially

c                    0    0

At equilibrium

(c-x)                x   x

The expression of dissociation constant :

:

was the of ethylamine value calculated by the student.
